In the midst of the current rom-com revival, Prime Video's The Love Hypothesis stands out as something of a delightful anomaly. Adapted from Ali Hazelwood's bestselling novel—which famously began as a piece of Star Wars fan fiction imagining a romance between Rey and Kylo Ren—the film carries a playful wink to its origins. There's even a fun bit of irony in casting Tom Bateman, who is married to Daisy Ridley (the real Rey), as the brooding love interest originally inspired by Adam Driver's Sith Lord.
Director Claire Scanlon and screenwriter Sarah Rothschild lean into that history with subtle nods—Bateman's character is almost always dressed in black, for starters—but you don't need to know the book's backstory to enjoy what's on screen. What you get is a thoroughly charming romantic comedy led by a winning Lili Reinhart and a surprisingly layered Bateman. While the final act tries to wrap up every loose thread a bit too neatly, it doesn't dampen the joy of watching two people fumble through a fake relationship that slowly becomes all too real.
What's the Story?
Olive Smith (Reinhart) is a PhD student at Stanford, driven by the loss of her mother to pancreatic cancer to pursue research that could make a difference. She quickly befriends fellow student Ahn (Rachel Marsh) and nurses a crush on another peer, Jeremy (Nicholas Duvernay). But when Ahn hesitates to pursue Jeremy because she thinks Olive likes him, Olive impulsively invents a boyfriend—and then, in a moment of sheer spontaneity, kisses the professor everyone calls "Dr. Evil."
That professor is Adam Carlsen (Bateman), known for being harsh and intimidating. Surprisingly, he agrees to play Olive's boyfriend, but not out of kindness. He needs to convince the department heads that he's putting down roots, which would secure him a lab grant. So they strike a deal: fake dating for mutual benefit. As they navigate increasingly elaborate performances for friends and colleagues, the lines between pretense and genuine feeling begin to blur.
Chemistry That Carries the Film
From the opening scene, it's clear that Reinhart and Bateman have something special. Reinhart's Olive is sweet, sharp, and endearingly idealistic, but her comedic timing is what truly makes the character pop. Bateman starts off almost too rigid, but he gradually peels back Adam's layers, revealing a vulnerability that makes his eventual fall for Olive believable. Together, they're a fantastic duo—both romantically and comedically—and their connection only deepens as the story progresses.
The film also bucks the rom-com trend of sidelining supporting characters. Ahn remains a vital presence, anchoring several key emotional beats, and Rachel Marsh brings both humor and heart to the role. Jaboukie Young-White, as Olive's roommate Malcolm, avoids the usual stereotypes, delivering a performance that balances wit with genuine depth. The movie takes time to explore Olive's friendships, reminding us that her relationships beyond romance matter just as much.
If there's a weak spot, it's the rushed third act, which tries to tie up every subplot with a neat bow. But by then, you're so invested in Olive and Adam's journey that it's easy to forgive. The Love Hypothesis is a near-perfect rom-com experiment—one that proves the genre still has plenty of life left.
