A scientist’s “worst mistake is a false positive — thinking something’s happening when it isn’t.” But in the official trailer for Prime Video’s upcoming film adaptation of Ali Hazelwood’s bestseller The Love Hypothesis, starring Lili Reinhart and Tom Bateman, the platform explores what happens when there is actually something happening between two people in their own unexpected experiment.

The Love Hypothesis, directed by Claire Scanlon, follows Olive (Reinhart), “a brilliant Ph.D. candidate focused on her future in academia. But when she realizes her best friend Ahn (Rachel Marsh) has fallen for her crush Jeremy (Nicholas Duvernay), Olive impulsively kisses intimidating professor Adam Carlsen (Bateman) to prove she’s moved on.”

In the trailer, Reinhart‘s Olive is shown spontaneously kissing Bateman‘s Adam — a notable Easter egg to the book cover of Hazelwood‘s bestseller — so her best friend Ahn can see them. Despite the initial awkwardness, Olive and Adam later agree to fake date to ensure Ahn will pursue things with her crush Jeremy, someone Olive once had a crush on, now knowing Olive has since moved on. Meanwhile, Adam notes the fake dating scheme could benefit him given Stanford may not be renewing his grant because they consider him a “flight risk.“
