The Love Hypothesis

The Love Hypothesis is a romantic comedy adapted from Ali Hazelwood's 2021 debut novel, the runaway bestseller that turned the author into one of the most popular voices in contemporary romance. Lili Reinhart, of Riverdale fame, stars as Olive Smith, a driven biology PhD student whose carefully ordered academic life collides with her messy personal one when she needs, on the spur of the moment, to prove to her best friend that she is dating someone.

In a panic, Olive kisses the first man she sees, who turns out to be Adam Carlsen, a notoriously demanding young professor with a fearsome reputation across the department. To Olive's astonishment, Adam agrees to keep up the ruse, and their fake relationship blossoms into the kind of slow-burn attraction that fans of the book adored. Set against the competitive, often unforgiving world of graduate science, the film mines both comedy and warmth from two guarded people who keep insisting, less and less convincingly, that none of it is real.

Built around the beloved fake-dating trope that helped make the novel a BookTok sensation, the adaptation leans into the chemistry of its leads and the specific texture of lab life and academic ambition. A crowd-pleasing charmer aimed squarely at the book's enormous fanbase, The Love Hypothesis is streaming on Prime Video.
