Romance fans have something exciting to look forward to this September. The Love Hypothesis, the screen adaptation of Ali Hazelwood’s New York Times best-selling novel, is set to stream globally on Prime Video beginning September 23.
Starring Lili Reinhart and Tom Bateman, the film brings one of contemporary romance fiction’s most popular fake-dating stories to life, complete with awkward chemistry, academic pressure, and feelings that quickly become impossible to ignore.

A Fake Relationship Starts With One Unexpected Kiss
At the center of the story is Olive, played by Reinhart, a brilliant Ph.D. candidate determined to stay focused on her future in academia.
Her plans take an unexpected turn when she realizes that her best friend Ahn, portrayed by Rachel Marsh, has feelings for Olive’s crush Jeremy, played by Nicholas Duvernay.
Hoping to convince Ahn that she has already moved on, Olive acts on impulse and kisses Adam Carlsen, an intimidating professor played by Bateman.
It is a split-second decision that creates a much bigger problem.
Soon, Olive and Adam find themselves entering a fake relationship built on carefully agreed rules, clear boundaries, and a setup that appears useful for both of them.
At least, that is the plan.
When Pretending Starts to Feel Real
What begins as a convenient arrangement gradually becomes more complicated as Olive and Adam spend more time together.
Their fake relationship may have started with practical intentions, but the emotions that follow are anything but simple.
As the difference between acting and genuine attraction begins to fade, Olive is forced to reconsider everything she thought she understood about relationships.

For someone used to testing theories and looking for clear answers, love becomes the one hypothesis that cannot be easily controlled.
Warm, witty, and filled with romantic tension, The Love Hypothesis explores what happens when two people agree to pretend until the feelings are no longer pretend at all.
