Interstellar and Coherence are both science fiction movies. They each use science as a jumping off point to tell an unusual story. They each require our suspension of disbelief in order to think about some aspect of humanity the story is trying to illuminate.
In some ways, they’re very different though. Interstellar uses lots of expensive special effects and employes lots of expensive movie stars. Its budget was $165 million. Coherence uses no special effects and no movie stars. It was filmed in the filmmaker’s own house, the cast outnumbered the crew, and it had literally no budget. The budget is officially listed as “not applicable.” Another key difference between these films is that Interstellar is an excruciating disaster while Coherence is a gem.
I’m not claiming that a work of fiction even needs to be scientifically accurate. It’s possible to make a compelling, interesting story with fantasy elements, and often “sci fi” is really just fantasy with sciency sounding stuff in it. Or inspired by something from science, but not completely accurate to real science.
Interstellar tried very hard to do science right. Physicist Kip Thorne was an advisor on the film, and he had the special effects team create the visuals for the black hole using a complex set of real physics equations. Wikipedia says: “The resulting visual effect provided Thorne with new insight into the effects of gravitational lensing and accretion disks surrounding black holes, and will lead to the creation of two scientific papers, one for the astrophysics community and one for the computer graphics community.”
Coherence, on the other hand, took the (real) idea of parallel universes from quantum physics and used it as a fantasy element. It explores the idea of multiple universes in a way that’s very interesting as a story, but that doesn’t make sense as hard science.
The irony here is that Coherence is a much smarter film. Interstellar is in the uncanny valley of science. In visual arts, the term uncanny valley refers to a character that’s just human enough to look kind of realistic, yet just “wrong” enough to be creepy and scary. You can make a character look realistic or cartoony, but if it’s almost realistic, it’s really uncomfortable to look at. Interstellar is trying so incredibly hard to be legit science that its missteps are cringeworthy and difficult to watch. Coherence, by contrast, takes one leap of fantasy-inspired-by-science then follows its own rules well and has its characters think about their situation in a smarter fashion than the awful dialogue in Interstellar.
There’s a reason that the characters in Coherence talk to each other in a believable way: because they are actually talking to each other. They aren’t reciting lines of a script to each other because there is no exact script. Each actor was told what their character would know at that point and given a page of notes from the director such as “you really want to go outside” or “you want to tell a story about X thing.” The actors did not know what events would happen around them during each scene. Instead, they are genuinely experiencing those events and they are genuinely talking to each other about what it means and what they should do about it.
That’s an interesting experiment when it comes to acting and filmmaking, and it didn’t have the result I expected. Having the whole thing improvised like that might make it feel “more real” (and I think it does), but this would be at the cost of clever scripting and plotting. If the author can precisely control every line of dialogue, they can work in more nuances, more double meaning, more foreshadowing, and have a tighter plot in the end. Or at least I thought that would be the case, but somehow Coherence has all of that too. It’s a movie that reveals more the second time you watch it, and I think it would reveal more even the fifth time. It’s a tightly packed puzzle of a movie, yet also a freeform improv.
Interstellar has an actual script, and in that script are lines that no one involved in science would ever actually say. The dialogue from the fictional world’s leading scientist (played by Michael Caine) are kind of insulting to our intelligence, almost like the writers of The Big Bang Theory snuck in. When asked how he was making advancements in his research, he said that once a certain gravitational phenomenon happened on Earth, it made him realize that such a thing was possible. So then he was able to develop new equations and better understanding and so on. But that he hadn’t yet “solved gravity.” Once he does, he says, then he’ll be able to do the fantastical things with it that the characters need. When asked how close he is to “solving gravity,” he says very close, and promises that he’ll solve it by the time one character returns from a trip.
This whole thing is so face-palm-inducing. Imagine if a new chemical compound was discovered, and you want me to synthesize more of it. I tell you that I’m working on “solving chemistry” to do that. Then before I “solve chemistry,” I’m able to give you some kind of progress bar like “chemistry 85% solved!” and a projection that it will be solved in one month. The problem is that I’m not able to know how close I am to discovering something I haven’t yet discovered. I’m not able to tell you when I will discover it. These are the wrong kinds of questions to even ask. Furthermore, the binary notion of gravity (or chemistry) solved / not solved is simplistic and childish.
Kip Thorne may have lent credibility to visual depiction of black holes and so on, but on a much more basic level, he really should have been consulted about how smart people attempt to solve a problem, how they would talk about solving a problem, and what solving a problem even really means.
SPOILERS OF INTERSTELLAR
The rest of this post contains spoilers for Interstellar, followed by another section of spoilers for Coherence. If you haven’t seen either movie, I’d recommend reading the spoilers for Interstellar, because seriously whatever, but not for Coherence. You can watch Coherence on Amazon Instant Video, here.
Yes I know that Michael Caine’s entire plan to “solve gravity” was intentionally a hoax. That doesn’t excuse anything I said above though. He went to absurdly great lengths to make everything about his actions and research as believable as possible. In fact, too great of lengths. Apparently, the entire building NASA is housed in he designed to be a giant centrifuge capable of being launched into space to function as a space station. Even though he knew that this was all a hoax and that the building would never be used that way, he seems to have actually made it really capable of that, and it ends up working correctly after his death. Yet he talks to other scientists with a childish, elementary school concept of what it means to do research.
That said, I think his whole hoax is interesting, story-wise. All his life’s work is a lie, and intentionally so because he knew that humans needed to be lied to in order to get them to do the work needed to save the human race from extinction. In the specific scenario his world is in, I think he’s probably right. It was probably morally correct of him to do so, and at the very least, it’s arguably defensible as such, and that’s interesting to think about.
And while I’m saying some good things, it’s cute that John Lithgow told Michael Caine that Murph makes the teachers at school look like fools, and if she joins NASA then they’ll make Michael Caine look like a fool. At the moment he said that, Murph was just a child, but she grows up to do exactly that. And for more foreshadowing, John Lithgow also told Matthew McConaughey (his stepson) that Matthew had an incredible skill and then the world changed and he never got to use that, and he’s truly sorry it worked out that way. Yet Matthew McConaughey did get to use his piloting skills and engineering knowledge, and he saved the entire world because of it.
Badly Written, Badly Edited
Let’s talk more about how badly written and edited Interstellar is.
That whole thing about how Michael Caine’s work is all a lie was revealed to us when he was on his deathbed in the hospital. The music told us that this was important moment and so we should listen carefully. I did listen carefully. I strained. Michael Caine mumbled some incomprehensible words for this big reveal. I wasn’t sure if he said what I thought he did. Murph (incidentally, that’s a stupid name) reacted as if she heard it though, and that it was a big deal. I pieced together what was going on, but couldn’t they have shot a second take of this? Or given me some subtitles? I just don’t understand why such an important moment is delivered with mumbly slurred speech.
Instant Friends and Instant Life Decisions
Matthew McConaughey goes from meeting NASA and being afraid they are going to kill his daughter to suiting up for a mission into space that will have him leave Earth forever in the space of...one day. At least I think it’s one day, I was unable to tell due the poor pacing and editing during this part of the movie. Did he really become chummy and start palling around with the crew THAT quickly? Like the same day or something or the very next day?
So Like, When Someone Buys Too Many Scratchy Lotteries?
Matthew McConaughey then leaves Earth in the old-style Saturn V-looking rocket, headed for an outpost near Saturn. Yet later they have spacecrafts capable of easily launching off planets into orbit, so why didn’t they use these here? Anyway, the reason they’re going to Saturn is to access the wormhole that appeared there 40 years earlier and that has been there ever since. Through the wormhole is another galaxy containing new worlds we could potentially colonize. Some are near a super massive black hole (SMBH) called Gargantua, and this has very important time-dilation consequences that are actually a real thing in science.
Ok fine, but here’s the thing. We’re really supposed to believe that the first time Matthew McConaughey even heard about this black hole or heard the word “Gargantua” was after they had already reached Saturn and were about to go into the wormhole? I actually said “what?” out loud at this. It’s just really poor writing to present it that way, because surely he would have been briefed on wtf they are even doing way, way before that. I also understand we need an audience-surrogate so the film can explain things to us, but using Matthew McConaughey this way compounds the bad-writing problem I just mentioned. When the other scientists explain what’s going on to him and he says lines like “oh so it’s like looking around with a periscope on a submarine,” it’s almost like he’s intended to play the same role as Ice-T on Law & Order: Special Victim’s unit.
Did You Hear That Music Too?
At one point, Matthew McConaughey watches a video of his son who says that this is the last video he’ll be sending. The music is very loud during this, really awkwardly and noticeably loud. The exact instant the son’s video ends, the music suddenly ends too. Was the music intended to be IN the son’s video?? It was edited as if it was, but that doesn’t make sense? Would the son really add incredibly loud dramatic music to his own webcam video? Did someone from NASA do it for him? Are we intended to think the music was in our movie, but not in his video? Why is this edited so poorly that I am asking myself these questions instead of paying attention to the movie?
The loud music thing happens a lot in this movie. It seems like they’re trying to contrast sounds with silence, which was an effective technique in the movie Gravity (sidenote: go see that movie instead of this one), but is so over-the-top here as to pull me out of the experience. Several times I thought to myself “why is the music or background soundscape so loud and distracting right now? Is something wrong with the theater’s speakers? No, because all the rest of the dialog and sound effects are the proper volume, so really it’s intended to be this distracting right now? Shouldn’t I be thinking about the situation going on in the movie instead? Is this a first pass edit rather than the theatrical release? Hmm, but I’m in a theater.”
Tidal Forces and Lack of Foresight
The situation with the watery planet makes no sense. First, a minor point where the science might make no sense, then a huge, glaring plot-destroying problem.
The water planet is in a gravity well of a super massive black hole such that one hour of time passing there is equivalent to 7 years passing on Earth. Time dilation from differences in gravity is a real phenomenon, and even measurable in fractions of a second per year when real astronauts go from the low gravity of an orbit to the standard gravity on the Earth’s surface. Ok so far.
If gravity is that intense though, it seems like it would be pretty hard to blast off from the surface of that planet to escape the high gravity region. It already makes no sense that this journey began with an old-style rocket when later on they had spacecraft that could easily take off a planet surface, but now the craft can escape the mega-massive gravity here easily?
It’s possible I just don’t understand enough of the real physics to explain that. I also thought that they’d just be crushed by the gravity, and that later on when Matthew McConaughey crosses the event horizon, he’d be spaghettified, as Stephen Hawking called it. “Tidal force” is a term that refers to the difference in the pull of gravity on one part of something and another part. It’s what makes our tides go in and out. Here’s a video about that:
The difference in gravitational force on your head is different from the force on your feet because your feet are closer to the center of the Earth. This differential, called a tidal force, would be so large when nearing the event horizon of a black hole that you’d be stretched like spaghetti and destroyed. That said, this isn’t true for all black holes. Super Massive Black Holes (SMBH) actually have less density, not more density, than their less-massive counterparts. They can be so large and so diffuse that a person on the surface of the Earth and one at the event horizon of a 10 million solar mass black hole experience about the same tidal force between their head and feet. So Matthew McConaughey might have been able to cross the event horizon without being spaghettified and maybe, somehow, this explains the gravity on the water planet being normal enough that you’re not crushed just by being there. I still question whether it explains the spacecraft being able to escape this super intense gravity well though.
We’ll let that one go. But not this next one. The characters see that the explorer on the water planet was already dead, then realize she must have been dead for only a few minutes from her perspective. She was only on the planet long enough to send the data from it once, not over and over across a period of many years.
Think about that. Before the characters reached this planet, they knew all about the time dilation effects of going there. When analyzing the data they got from the planet, they knew about this time dilation situation. That means they knew how many packets of annual data they expected to receive: one packet. What they actually received was many packets which would indicate years of data sending. They specifically mention this because it was an indicator that the explorer was still alive because she had been sending data all this time.
So a) they would have known that they only had the first year of data, not other year’s worth, b) they would not have expected to receive lots and lots of years of data, c) they DID receive years and years of data, which they should have realized makes no sense at all. The script hand-waves past this by saying the discrepancy between “data was sent once” and “data was sent many times” is explained because the data was caught in some sort of “gravity echo” or something and it was just the same signal repeating itself over and over. Mega face palm, and insulting to the audience. It’s a stupid non-explanation and even it were real, it still wouldn’t explain why anyone expected to gets years of data in the first place. This whole thing just doesn’t work, plot-wise.
The Data-Revealing Robot
Matt Damon’s robot. Matt Damon tells the other characters that he took his robot apart to get to the fuel cell so he could continue with his mission. When the crew’s robot offered to fix his robot, he discouraged this and said it needed “a human touch.” We later learned he meant that literally, that it needed the thumbprint authorization from a human to activate the decommissioned robot.
I don’t really get any of that, but I’ll give it a pass anyway. Here’s the thing: what was Matt Damon’s actual plan with sabotaging this robot? I get the general idea that the robot contained data showing that Matt Damon was lying about the status of the planet, so apparently he rigged the robot to self-destruct in a big explosion if anyone tried to access that data. When did he do this? It seems impossible for him to have had the time after he was revived, so I guess he did this a long time ago before he went into hibernation.
Ok but, then why did the robot immediately display the most damning data when a human did put their thumb print on it? I assume he programmed it not to explode if he used his own thumb, but if it’s someone else’s thumb, then he set it to automatically show them the exact data he needs to hide, THEN explode? This is really sloppy writing. The writers want to let us know that the data is in there, and have the drama of a character discovering this, but it makes no sense for Matt Damon to have set it up that way.
Incidentally, I really like that Matt Damon’s character lied. Michael Caine (who also lied about his entire mission) told us that the 12 explorers were the bravest humans who ever lived and that Matt Damon’s character, named Dr. Mann, was the greatest of them all. But then Mann turned out to actually be a coward who would do anything to save his own skin, at any expense. (Mann is mankind, get it?)
Way, Way, Way Too Many 0s and 1s
Behind the bookcases. So inside the black hole, is a crazy 5th dimensional space that far future humans constructed so that Matthew McConaughey could talk to his daughter. Uh, well, ok. There are just several awkward things here.
Matthew McConaughey first uses the bookcases to see himself in the past before he went on the mission, and he tried to tell himself to STAY, as in not to go on the mission. He fails though, and his earlier self does go. Then he realizes that he can use this whole setup as a way to communicate information to his daughter Murph. It’s awkward that he must communicate quantum data from a black hole though. Probably like terabytes of data in who-knows-what-form, converted to just 0s and 1s? Does this take like 9000 years? How does she even make sense of that? I feel like if he had sent her the 0s and 1s for the computer code behind Microsoft Word, that she wouldn’t have been able to understand that and create Microsoft Word any more than she could make heads or tails of “quantum data.” Why wasn’t the message something more human, like an inspiration for her to research the right kinds of things? Or an equation, at most. I guess because it had to be something they discovered *on* the mission, which means data from the black hole. That’s a tough writing problem, and the writers took the way out that required the least thought and delivered the most disappointment to the viewer.
Love Conquers All
Let’s jump back to an earlier part of the movie involving Love Conquering All, then return to the bookcases. Matthew McConaughey, Astrophysics Black Guy, and Anne Hathaway must choose whether they visit Mann’s planet, or Edmunds’s planet, but they can’t choose both with the fuel they have left. Literally the fate of all humanity rests on this decision. Matthew McConaughey calls out Anne Hathaway as being biased because she’s in love with Edmunds. She admits that this is true, but argues it’s still the correct decision. Both planets sent good data, and the one she wants send slightly better data. The drawback is that they stopped getting communication from Edmunds at some point, while Mann has still been sending data. Maybe Edmunds’s communication equipment broke, or maybe he died, but either way that planet looks a bit better. Furthermore, love is powerful and worth something and might give us access to mystical information that we can’t otherwise divine. Something deep is telling her she’s right to choose this planet, not Mann’s, and that should be considered too.
I actually think that’s an interesting argument. It reminds me of my work in balancing games when people argue and claim opposite things. Sometimes people on one side bet everything on some sort of data or calculation, saying that proves their stance is more solid. The problem comes when the other side is relying on intuition or factors they can’t verbalize, when the first group is *neglecting* subtle factors that weren’t part of the calculation. Matthew McConaughey decides to “go with the data” (by valuing Mann’s data more because he’s still sending data each year) and yet it turns out to be the wrong choice in the end. Maybe Anne Hathaway just got lucky with the right answer, or maybe love really did tell her something. Thematically, I like that.
Hamfisted Love Conquers All
Love Conquers All again back at the bookcases, but this time it’s much more hamfisted. McConaughey’s dialogue about this is just corny. When confronted with a bizarre, surreal bookcase-world that crosses boundaries of time and space, he immediately claims he can navigate correctly because of his love for his daughter. Come on now. I’m fine with “love conquers all” but not when expressed in such a hokey way.
The story from Murph’s perspective is just as silly. From her perspective, she has gone her entire life without even considering that the “ghost” she remembers from her childhood was actually her father from the future. So she returns (as an adult) to the place where the ghost told her things, but can’t seem to get anything from it. Then she suddenly realizes it’s her father. Again, I actually said “what?” out loud. She had no clues and no information at all what was going on, or even that anything was going on. She suddenly and magically just knows.
I understand the movie’s intention here. The idea is that gravity is one of the only things that can cross from a 5 dimensional space to our world and potentially be used to send messages. (That actually has some real basis in physics, btw.) And the implication here is that perhaps *love* is able to do this as well. Perhaps it also can cross the boundaries that we thought were uncrossable. Ok, that’s thematically appropriate if you’re doing a Love Conquers All story and it need not be scientifically accurate. But it should be shown in an understandable and at least emotionally believable way. Here she is staring at the same bookcase she had known for 20 years, but now, for no apparent reason, has exactly the correct revelation about her father. This part of the movie really should have shown her noticing some clue that helped her connect the dots.
Carelessness With the Most Important Object in the World
Matthew McConaughey uses the wrist watch he gave Murph to transmit the quantum information. Then soon after, Murph talks to her angry brother. This guy is pissed off, told her to leave forever. Ten seconds ago het got back from putting out a fire in his fields that she started on purpose. Meanwhile, she holds up the watch—THE WATCH. It’s literally the most valuable object in the entire world and the only thing that can save the entire human race from dying. It is LITERALLY that. She waves it around in front of the emotionally unstable and angry brother as she tells him some nonsense about the ghost of her father sending info to her in the watch. I actually cringed at this, expecting him to grab it from her and smash the watch. Then she tries to hug him and I expected him to punch her lights out and somehow ruin the watch. This isn’t even intentional dramatic tension though, just case #127 of bad writing in this movie. Case #128 is when the brother’s reaction to all this is to passively hug the sister instead of saying “wtf are you even talking about?”
Matthew McConaughey claims (suddenly and randomly, by the way) that the 5 dimensional bookcase zone was built by far future humans, not by aliens. How did he know this? I have no idea. I didn’t see any indication of this, but I guess he just knew.
Ok, so when did they build it? In the far future. So let’s think that through. After the end of the movie, humanity was in a position to continue on. Great! So they do, and then way in the future, maybe like millions of years or more, humans “evolve into 5th dimensional beings.” Let’s not even question that. Ok so the 5th dimensional being thing happens, and they are all hanging out. Maybe at a 5th dimensional Starbucks, drinking Pumpkin Spice Pure Energy. One of them says, “hey, remember in the history books—well I know we don’t have a concept of books or even of history since we can now experience all time as a physical dimension, but you know what I mean. Anyway remember how the humanity was going to be destroyed way long ago? The only reason that didn’t happen was that at some point we got around to building a 5th dimensional bookcase thing for this one guy. Should we get that going? Or just wait a while on it?”
This is never even addressed in the movie, but it’s just really head-scratchy. Like what the hell is the timeline even supposed to be here?
The Great and Needless Heist
At the end, Matthew McConaughey goes to visit Anne Hathaway’s planet to join her. This is thematically very appropriate because his character represents the human spirit of exploration and it’s exactly what he’d do. Come to think of it, I guess he embodies the American spirit of pioneering and exploration, and he ends up in a new world with an American flag in it. Very American.
Anyway, in order to make this happen in the plot, he STEALS a spacecraft to go to her. He is living in a world foreign to him that’s 100+ years more advanced than what he’s familiar with. Does he really know how their docking system and aircraft hangar system work? Will he be shot down? What weapons does the space station have? Can they track him? Wouldn’t there be some kind of mission control room with radar and alarms that go off if he tried to do this? But the actual way it’s conveyed to us that anyone knows the spacecraft was stolen is that a guy with a clipboard wanders by the part of the hangar where that spacecraft was supposed to be and notices it’s missing. Sloppy writing #935.
So Wait, What's Happening Now?
And let me end all of this madness by going back to an earlier moment of confusing editing and unfortunate writing. Just before Matthew McConaughey enters the black hole to get to the bookcase area, he and Anne Hathaway start their journey back to Earth. We are told they need to get rid of some weight to do this, so they get rid of the robot. Matthew McConaughey then suddenly reveals his plan to leave himself behind too, so that Anne Hathwaway can get back home.
The moment of this reveal is so poorly edited that I thought, “wait, I thought he was on the same ship as her? They are on different ships actually? And wait what is going on here, he’s suddenly sacrificing himself?” I later asked a friend about this exact moment and she also though they were on the same ship until he revealed that he was leaving himself behind.
This is not some minor plot point though. Matthew McConaughey’s character is driven, even obsessed, with saving his daughter and returning to his family. He wants to save the world, but he uses the drive to save his family and see them again to push himself to keep going. Every action he’s taken up to this point has reinforced that and this is the FIRST moment that he abandoned his goal of seeing his family again. In his mind, he is sacrificing himself and he’s about to die because of it. And yet this is kind of sprung on us with not enough time to really process it or to even understand that he could have done that because it’s unclear where he is relative to Anne Hathaway.
Matt Damon’s character dies suddenly too, but that’s fine and on purpose, while the hasty treatment of the main character’s ultimate sacrifice just feels like an oversight.
This post is long, but that’s just because the movie is long. Long and filled with badly executed story. The best thing I can say about Interstellar is that if it were presented in the form of a one page pitch, it would probably sound really compelling. It’s all in the execution.
SPOILERS OF COHERENCE
You should watch Coherence first before reading this.
Whose story is it?
There are eight characters in this movie, and it might be unclear at first whose story it really is. It’s Emily’s story. If you rewatch the movie, this is even more clear. We start with Emily, and we end with Emily. What you might not have noticed though, is that we follow Emily and only Emily throughout the various alternate realities. Other characters are replaced with alternate reality versions of themselves and we visit alternate reality versions of the house, but it’s the same Emily all the way through—the story tracks her.
Everyone is in the Wrong House
Near the beginning, all the characters go outside, then come back in and there’s a broken vase, which someone says they don’t remember breaking. That’s a clever trick because at this point, we don’t know that going outside into the dark zone sends you through a roulette of universes. EVERYONE is now in a different house than they started in, before we even knew that was a thing. It doesn’t matter plot-wise, but it’s just kind of funny.
Random Events Are Markers for Each Universe
Hugh and Amir visit “the other house,” but a different Hugh and a different Amir return to our house. They don’t realize they’re out of place for a while, but the different color glow sticks tip them off. They have red glowsticks, but the box of red glow sticks in this house has never been opened. When they realize this, they leave and take the physics book and box of pictures with them because they figure they should take all the important information for themselves in an effort to return to their “right” reality.
The glow sticks, the band-aid being cloth vs regular, and the phones that have cracked screens vs don’t are all indicators of which universe is which. The idea is that infinitely many things could go this way or that way in quantum physics, each spawning a new reality, but these specific things are easy for the audience and characters to see and understand.
What’s smart is that the characters take things into their own hands by creating a marker for their house. They realize that it should be something based on randomness so that it will come out different in all the other houses. I think they cheat a little bit on the plot here, because the characters’ stated goal was an address for the HOUSE, but they actually created mini-addresses for each character too. I would think they’d roll several dice to create a house-address, but not an individual die for each person. We’ll let that go though; it turns out to be important to the story that we can tell which individual people are from which reality.
Who is Who?
Mike’s wife complains that Mike is drinking too much and says Mike is “not the man I married.” He literally isn’t because she’s now with a Mike from a different universe than hers.
Why Did Someone Break the Car Window?
Mike tells Kevin that he went to the other house to blackmail himself. He says he considered breaking the window of Hugh’s car in the other reality so that he could steal the physics book and prevent the others from having the conversation about other realities. But he says he didn’t actually do it. He didn’t, but later we see that another Mike from another reality DID do that.
Or did he?
When Emily returns to the house, the Mike from that house is trying to figure out why anyone would smash Hugh’s window when the book clearly wasn’t in there. Anyone could see through the car window that the book had already been removed, so there’s no reason to smash the window anymore. Someone else says maybe getting the book wasn’t the motive. Could it be some other reason, maybe intimidation?
By the end, we know why. Emily does it as a diversion to lure everyone outside in order to kill or incapacitate the other Emily.
Like A Ping Pong Paddle? Exactly.
Amir explains the idea of the quick codes, that putting a random object in the box helps create a better “address” code for the house. It could be a candle or a book, says. Or an oven mitt. Then Emily says “or a ping pong paddle.” Amir off-handedly says “yeah or a ping pong paddle, exactly.” Emily says, emphatically “exactly….”
What the characters and audience don’t know there is that Amir didn’t say oven mitt because that random object occurred to him at that moment. He said it because in his universe, the box he opened earlier had an oven mitt in it. Emily doesn’t know that, so she says “ping pong paddle,” as in “oh I get it, we opened a box with a ping pong paddle so that’s the quick code for that box.” Amir doesn’t realize that though and he thinks she’s naming a random object. She’s confused why saying “exactly” doesn’t get a better response from the other characters, but she doesn’t yet realize she’s in the oven mitt house, not the ping pong paddle house.
The Dark Versions of Us
Near the end Mike says, “This whole night we’ve been worrying there’s some dark version of us out there somewhere. What if we’re the dark version?”
This turns out to be true. Let’s look at the whole story now from Emily’s perspective.
Early on, Emily tells us how she created a dance production, but then she didn’t get to star in it. Katherine Meriss ended up in that part, became famous, and “stole her life.” Note that the reason Emily didn’t get the part is that when she was offered the understudy role (that would later become the real role), she took too long to say yes, so the yes became a no.
Emily’s husband Kevin will go on a business trip to Vietnam for four months. He wants Emily to come, but she’s hesitant. He says ok how about coming for just one month rather than the full four? She says she’s not saying no and that she’ll think about it. This is the same mistake: he says that doing nothing turns into a no.
Later in the evening, Emily takes more control of her life and her relationship with Kevin. When Kevin is going to go outside without her, she becomes flustered and demands to go with him. Even later, Kevin wants to go out without her again, and she physically blocks his way and very forcefully says that they need to stay together.
Eventually, Emily figures out that various people are from various different realities. Specifically, she and Mike are visitors in this reality, meaning Mike’s wife isn’t the wife he knows (and her husband isn’t the husband she knows either). Emily believes they must leave the house and take their chances with the reality roulette in order to get back to their own realities. Mike disagrees though. He says he’s made certain choices in life and is stuck with them. He’s stuck here.
This brings us to, “what if we’re the dark versions of ourselves?” Everything goes wrong, people are bickering and arguing and Emily sees it as a nightmare to be stuck in this reality. She takes charge and chooses to go shopping for a new, better reality. It’s implied that the clock is ticking too: when the comet passes, she’ll be stuck wherever she is.
The problem is that the happy reality she stumbles on has HERSELF already in it. There’s a line of dialogue in this “good house” about wondering if Katherine Meriss will understudy Emily’s life when she’s gone for a month. This tells us that in this reality, Emily didn’t wait too long to get the dancing part: she really got it and became famous. And she didn’t wait too long to decide to go to Vietnam with her husband either. These are the choices she “should have made.”
Will she kill in order to get that better life? The movie asks us an even deeper philosophical question here: will she kill HERSELF to get a better life? Is it ok to do so? Is it ethical or not? Does it even matter what happens to anyone, even “yourself” if they are in a different universe? It doesn’t seem ethically bad to stumble into these various realities, but by doing so you’re actually preventing other copies of yourself from getting to the good ones, so is it really even that much different if you force one of yourselves out of a good one? And if you kill yourself, is that even detrimental to you given that you the killer perceive that you live on anyway, and with no consequence?
I won’t try to answer those, but I will point out something Hugh said early on. He thought that his other selves would want to be left alone, so he thought it was best to leave all the other universes alone. Meanwhile, Mike thought it was best to murder his other self before his other self murdered him. Because there are so many Hughs and so many Mikes out there, this means that most Hughs are safe and most Mikes are not. It’s like karma made tangible.
In the end Emily is willing to kill to get the life she wanted. Even though her journey was one of growing confidence and taking charge of her life, we did see the dark version of her.
