Prime Video released a trailer Wednesday for the movie “The Love Hypothesis,” which is based on the 2021 book of the same name by Ali Hazelwood. 

The story, which features the popular grumpy-sunshine and fake-dating tropes, follows Stanford University Ph.D. candidate Olive (Lili Reinhart), who fakes a relationship with intimidating, brooding professor Adam (Tom Bateman). Olive thinks this plan will prove to her friend Anh that she has moved on, so Anh (Rachel Marsh) can feel free to pursue Olive’s former crush. Adam thinks this could help him with a situation at work, so the scheme seems mutually beneficial.

The trailer shows Olive and Adam trying to navigate fake dating and potentially real feelings.

Will sparks fly? Fans of the novel know the answer.

“The Love Hypothesis,” directed by Claire Scanlon and written by Sarah Rothschild, will premiere on Prime Video on Sept. 23.
