‘The End of Oak Street’s Fascinating Time Travel Rules, Explained

Warning: Spoilers ahead for The End of Oak Street!Movies that see eras collide on-screen via sci-fi-heavy means often contribute a new wrinkle to the beloved time travel trope, and The End of Oak Street is no different. While the film begins centered on a troubled marriage and youthful optimism about the future, events quite quickly reveal themselves to be far less run-of-the-mill. Written and directed by David Robert Mitchell (It Follows), The End of Oak Street is something of a deviation from his admittedly limited back catalog, but it still retains powerful elements of his psychological thrillers, despite a PG-13 rating.

All that being said, the time travel lore is definitely the most central to The End of Oak Street‘s worldbuilding. It can be easy to be distracted by the rampant dinosaurs and character-driven drama. The fact that Anne Hathaway’s Denise Platt and company have been sucked back millions of years into the past can fall into the background at times, and feel like little more than a vehicle for the story being told. However, the movie does provide at least some information on how its version of time travel works, and some of the parts that aren’t directly discussed can be figured out by context.

What ‘The End of Oak Street’ Officially Reveals About Its Time Travel Rules

Warner Bros. Pictures

I spent most of The End of Oak Street waiting to find out exactly how the Platt family’s entire neighborhood had been transported back to the Mesozoic Era, one of the three distinct periods where dinosaurs walked the Earth. I didn’t let the lack of information distract me from the story being told, but I was looking forward to an answer being provided. In that sense, I was a little disappointed. The End of Oak Street‘s ending does provide an explanation, but it’s very brief and arguably creates more questions. In short, the neighborhood went on its temporal adventures via a “naturally occurring wormhole.”

The reveal can be heard on TV during The End of Oak Street‘s epilogue sequence, which is set in 1984 – two years after the movie’s core events. The news report is looking back on the movie’s main storyline from two years earlier and recapping what’s since been discovered about the phenomenon. As it turns out, there’s been almost no progress. All the stray dinosaurs have been captured and/or killed, but Earth’s best scientific minds haven’t been able to figure out how the beasts got there, and how Oak Street and its neighborhood were sent back through time. By 1984, there had been no further events of even a vaguely similar nature, suggesting the wormhole that formed required very specific conditions that haven’t since been present.

From what we see of the wormhole(s) in action throughout the movie, it’s otherwise relatively simple. There appear to be two distinct kinds of wormholes. The first doesn’t just move something from one era to another, but also swaps it out with whatever is at that location at the time. This is most prominently demonstrated by the Platts’ entire neighborhood being sent back to the Mesozoic era, and the land on which said neighborhood would eventually be built is brought to the present. Another, smaller example of this first sort of wormhole could include the one that brought a steaming pile of dino dump into Mel’s (P.J. Byrne) backyard. Or, that original patch of Mel’s yard could have been sent back in time, and replaced with the horrific mess.

The latter is more likely, and probably also applies to the unusual plant that Denise and Mrs. Huddleston (Anne Gee Byrd) struggle to identify. The second type of wormhole is the one that allows Denise and the three kids in her care to escape back to 1982. Seemingly at random, translucent orbs large enough for a person to jump into spawn nearby, within the neighborhood that’s displaced in time. It stands to reason that the same thing is also happening in the present day, given that they all seemed to have an ejection point in the 1980s. They don’t last forever, and it’s impossible to predict where one might pop up next. While narratively convenient, I’m sure Denise and company didn’t mind about that, and were just content to find a way back to their native time.

Greg’s Temporal Resurrection in ‘The End of Oak Street’ Has Dark Implications

Warner Bros. Pictures

The strained marriage between Greg (Ewan McGregor) and Denise is one of the first subplots The End of Oak Street introduces, implying that one of the movie’s most wholesome developments will be that they’ll figure things out by the end. They did, but not in the way that I imagined. Because the movie spends so much of its time masquerading as a Spielberg-esque family-friendly romp, I figured its PG-13 rating wouldn’t allow for any major character deaths. Even the neighbors being torn to shreds on screen felt like it was pushing the boundary of the age rating, but they were shot as relatively bloodless demises. So, when McGregor’s character was eaten alive by a dinosaur while his family watched in horror, I was genuinely shocked.

Even though I was watching a movie where time travel exists, the total lack of control the characters had over moving between eras made me wonder how or if Greg would be able to come back. I quickly settled on no, he wouldn’t. But what a fool I was. When Denise guides her remaining cohort back to 1982 through one of those smaller wormholes, their arrival 20 minutes before the neighborhood was swapped out for a patch of land rife with extinct species meant she was able to get the word out to everyone she saw perish in the past she’d just left behind. Part of this development involves her calling the still-alive Greg, or more accurately, the pizza company he works for, to make a delivery to the spot on the hill where they’re about to watch their home vanish. We won’t talk about what would have happened if the pizza company had sent a different delivery guy.

While the reunion of the Platt family is treated as this super wholesome thing, that’s only the surface interpretation. Once the neighborhood goes back a second time, it does so without this other version of Greg. So, the events in the past would go differently. The Platts would be down a man in their fight for survival. Furthermore, Denise warns the other neighbors she saw die, and we know from the news report in the epilogue that they all got out alive as well. One such neighbor helped Denise and the kids on their final charge to the wormhole that saved them by gunning down the dinosaurs in their way. Without her there to do that, Hathaway’s character and the three kids with her would most likely have perished during that sticky situation – if they even got to that point without Greg.

In other words, the Platts we see at the very end of the movie made their family whole again, but possibly at the expense of the alternate Denise, Bryan (Christian Convery), and Audrey (Maisy Stella). While we know their neighbors were notified about the pending danger and therefore survived, there’s no confirmation that the other Denise and her two kids were told to get out of the neighborhood. That being said, I refuse to believe that Denise would let any version of her kids be in danger if she could have helped them. Therefore, it could be that there is another Denise, Bryan, and Audrey out there who escaped from the neighborhood and are living on somewhere else. If so, they’re doing it without the version of Greg who technically belongs to them. Either way, The End of Oak Street‘s time travel rules give the movie an ending that’s morally ambiguous.

Is ‘The End of Oak Street’ a Time Loop Movie (Or Is it a Multiverse Movie?)

Warner Bros.

I’ve thought about this a lot, and it arguably depends on how you look at it. The End of Oak Street could easily be described as a time loop movie, given that if those in the past continued to find wormholes that brought them back to 20 minutes before the swap happens, the loop would carry on indefinitely. For instance, when the Platts watch the temporal swap from the hillside at the end of the movie, the versions of themselves who were taken back in time as part of that version of their neighborhood would experience a very similar version of events to the ones the movie just showcased. They wouldn’t be identical, though.

If Denise hadn’t intervened by making all those phone calls, then what happened after the temporal swap would have occurred exactly as we’d already seen it, including Greg’s death and Denise guiding the same survivors to the exit wormhole. That would definitely qualify as a traditional time loop. It’s because Denise warns people and alters the population of the doomed neighborhood that it will suffer a different fate after it’s sent back through time again. In this sense, an alternate timeline is created, or a new branch of reality. This would be easy to describe as a sort of multiverse, but it depends on whether The End of Oak Street has just one established timeline that can be altered, or if a new reality spawns with every change made.
