Lili Reinhart and Tom Bateman star in The Love Hypothesis, and the romantic comedy has now topped Prime Video’s US rankings after its September 23 premiere. The film is based on Ali Hazelwood’s bestselling novel, which began life as Star Wars fan fiction centered on Kylo Ren and Rey before becoming a publishing sensation on its own.
From Fan Fiction to Bestseller
The Love Hypothesis started as fan fiction featuring Kylo Ren and Rey, two characters from the Star Wars universe. The story then evolved into a standalone novel. The book’s success allowed it to stand apart from its sci-fi origins.
The story follows Olive, a Ph.D. candidate who impulsively kisses her department’s most intimidating professor, Adam Carlsen. Their mutual need for a fake relationship turns into an experiment in chemistry that might actually solve for love. As a romantic comedy, the experiment eventually produces results neither of them included in the hypothesis.
The Fake Relationship Premise
Olive and Adam start with a fake relationship, a setup straight out of the rom-com playbook. The premise asks whether a fabricated romance can become real through chemistry.
Reinhart plays Olive, and Bateman plays Adam Carlsen. The supporting cast includes Rachel Marsh as Anh Pham, Nicholas Duvernay (Bel-Air), Jaboukie Young-White (Only Murders in the Building), Arty Froushan (House of the Dragon), Aadi Maaj, and Jeananne Goossen (The Night Shift).
The Star Wars Connection
The film’s origins in Star Wars fan fiction are notable. Hazelwood’s novel began as stories pairing Kylo Ren and Rey, characters central to the franchise’s recent films.
The romantic comedy genre has a long history of borrowing from other properties, but few start with such a direct link to a major franchise. The adaptation moves the story from a fascist space government and a patricide element involving a smuggler dad into an academic setting.
Why the Ranking Matters
The film’s No. 1 position reflects its immediate appeal. A new release topping a streamer’s rankings is a strong indicator of audience engagement.
The ranking also shows how quickly a film can move through a crowded catalog. Prime Video offers a wide selection, and a new title reaching the top spot signals strong demand.
The Cast and Its Reach
Reinhart is known for her role in Riverdale. Bateman appeared in Based on a True Story. The supporting cast draws from a range of recent television work.
The film brings together actors with established credits across streaming and cable television. The mix of young stars and character actors gives the project a broad appeal.
A Romantic Comedy Built on Chemistry
The core of The Love Hypothesis is its experiment in chemistry. Olive and Adam start with a fake relationship, and the story tracks whether that fabrication can become genuine.
The film’s position atop Prime Video’s rankings supports that reading. Audiences appear to enjoy seeing a fabricated romance tested in a controlled setting.
