Movie delays happen all the time in Hollywood, especially in the last few years. But when Warner Bros. pushed David Robert Mitchell’s Flowervale Street, a sci-fi film with Anne Hathaway, Ewan McGregor, Maisy Stella, and Christian Convery, from May 2025 to March 2026 and then to August 14, 2026, people started asking questions and coming up with their own wild theories regarding the delays. And mostly because no one actually had the faintest clue what this movie was about. There are no real images, no trailer and no synopsis yet for the film. Nothing. All we really have is title (which has now changed to The End of Oak Street) and a few set photos of the really great cast.
Reddit even had theories it was a secret Cloverfield entry, thanks to J. J. Abrams’ Bad Robot producing. Turns out, those Redditors were… kind of right and kind of wrong. According to World of Reel, the mystery project is a time-travel dinosaur movie.
Until recently, all we knew was that it was an “‘80s-set thrill ride” with a budget circling $85 million. Rumors of dinosaurs floated around, but Ewan McGregor himself tried to pour water on the fire in an interview with Collider: “Well, I don’t know where they’re getting dinosaurs from. That may or may not be the case. But no, I like [David Robert] very much, this film director, and I like very much the idea of working with Anne Hathaway.”
Sorry, but it seems Obi-Wan lied. The dinos are real.
Here’s the plot breakdown according to online rumours: McGregor and Hathaway play parents living on Flowervale Street. Their lives seem fairly normal until they start noticing strange shifts in their neighborhood. Then, after a violent thunderstorm, they somehow time-travel and wake up in the prehistoric era.
The film is described as tense but family-friendly, sort of like Spielberg’s Jurassic Park, in a way. Hathaway, by early accounts, steals the spotlight and looks like she’s having a blast on the sets.
Just a few months ago, Warner Bros. film studio heads Pam Abdy and Michael De Luca mentioned in an interview with The Wrap that Flowervale Street would probably undergo a name change. Well, it seems that’s true, too. It’s now rumored to be called The End of Oak Street.
Also, the delay, it seems, wasn’t actually because the movie was a mess. Reports from early test screenings suggested The End of Oak Street was already “90% completed” and well-received. Warner Bros. likely just wanted a better release window for what could be their big summer event movie.
For Mitchell, this project could be huge for his career, especially since his last film, Under the Silver Lake (2018), had a rocky road, marked by multiple delays and a domestic gross of under $50,000. Still, it earned a cult following that fans have been obsessing over for years. Mitchell is also set to return to horror with They Follow, the sequel to his breakout hit It Follows, with Maika Monroe back in the lead. If things line up, 2026 might be the filmmaker’s biggest and busiest year yet.
So, after years of radio silence, we finally know what Flowervale Street… I mean, The End of Oak Street… is… or at least could be about… a time-travel, dinosaur-packed, suburban survival flick with a nostalgic ’80s flavor.
