What To Know

The Love Hypothesis made Ali Hazelwood a household name in the romance world back in 2021. Since then, she’s published a number of other books about women in science finding love, usually with tall, aloof men who are secretly obsessed with them. It’s a formula that her fan base can’t seem to get enough of — and soon, it’ll make its way to the screen with a movie adaptation.
Very soon, in fact. Lili Reinhart, who serves as The Love Hypothesis‘ star and executive producer, recently offered fans an update about when the rom-com will arrive in theaters. We’ve been chomping at the bit for more details about The Love Hypothesis movie ever since it was announced in 2022, so of course, we’ve got everything you need to know about the adaptation below. Keep reading for Swooon’s full breakdown of all the details revealed so far, including the cast and release date.
When does The Love Hypothesis movie come out?
After keeping fans up to date during filming this summer via social media, Reinhart revealed that filming wrapped in a September 1 TikTok video.

A few months later, Reinhart shared that it won’t be long until The Love Hypothesis arrives in theaters. “See you in 2026 👀,” she wrote in a January 3 Instagram Story.
Who has been cast in The Love Hypothesis?
The cast list includes the Riverdale actress as Olive and Tom Bateman as her love interest, Adam Carlsen. Shortly after shooting wrapped, the latter opened up about bringing Hazelwood’s book to life. He realized how large and passionate the book’s fan base was during filming, explaining to People, “You just feel that love. So you’re making something, you think, ‘My God, people are really, really excited for this…’ It felt very special.”
Joining them is Adults star Rachel Marsh, who’s playing Olive’s best friend, Anh. The White Lotus‘ Nicholas Duvernay is Olive’s ex, Jeremy. Her roomie, Malcolm, is Companion‘s Jaboukie Young-White. Daredevil: Born Again‘s Arty Froushan is Tom, Adam’s friend and a Harvard professor.

Good news, book fans! Hazelwood is on board with all of the actors portraying her characters. “Oh my God, yeah,” she said when asked if she approves of the cast. “They’re amazing.”
What is The Love Hypothesis about?
The Love Hypothesis is about a PhD student, Olive, who enters into a fake dating situationship with Adam Carlsen, a professor at Stanford. Olive needs to convince her bestie that she’s over her ex, and Adam wants the Stanford faculty to believe that he’s not a flight risk. (He needs funding for a project, which will only come if he appears committed to the university. Having a girlfriend makes him seem more settled.)
As with all fake dating scenarios, the more time these two spend together, the deeper the connection becomes, and the harder it is for Olive to tell what’s for show and what’s genuine love brewing between them.
That’s what we know of the book’s plot, however. When Hazelwood shared her thoughts about the adaptation for the first time, she confirmed it wouldn’t be exactly the same. “Of course, it’s going to be different from the book,” the author said during a book event. “It’s a completely different medium, but it’s something that at some point passed through my head. It’s amazing.”
Who is making The Love Hypothesis movie?
Amazon MGM Studios and MRC are developing the film. Hazelwood herself is an executive producer, too, alongside Reinhart and Catherine Hagedorn. Elizabeth Cantillon (Charlie’s Angels) is producing. Director Claire Scanlon (Set It Up) is also on board, and she’ll be bringing Sarah Rothschild’s (The Sleepover) script to life.
“Honestly, I still can’t believe this is happening?” Hazelwood said. “Elizabeth Cantillon, Claire Scanlon, and Lili Reinhart have all created, produced, or starred in works that I’m absolutely feral about, and I am beyond honored that they’re choosing to bring their talent to this project. Books and films are very different media, and I have complete trust in this brilliant team. I cannot wait to see the final product they’ll come up with. I hope they have as much fun filming as I had while writing the book.”
