In the new streaming release, Reinhart plays Olive Smith, a PhD student who impulsively kisses her department’s intimidating professor, Adam Carlsen (Tom Bateman), to prove to a friend that her love life is fine. The kiss sparks a fake‑relationship arrangement with clear rules, which gradually blurs the line between pretense and genuine feeling.
The movie is based on Ali Hazelwood’s novel of the same name, a 2021 title that became a BookTok sensation after its origins as a Star Wars fan‑fiction were revealed. The book’s popularity helped secure a high‑profile adaptation starring two well‑known actors.
‘The Love Hypothesis’ became available on Prime Video at 3 a.m. ET on Sept. 23. The film is exclusive to Amazon’s streaming service, meaning viewers need an active Prime subscription. New users can start with a 30‑day free trial; after that, Prime costs $14.99 per month or $139 per year. A discounted “Prime for Young Adults” plan is also offered to 18‑ to 24‑year‑olds, providing a 50 % discount after a six‑month trial.
The supporting cast includes Rachel Marsh as Anh, Jaboukie Young‑White as Malcolm, Nicholas Duvernay as Jeremy and Arty Froushan as Tom. The production was reported by Angela Tricarico, a commerce streaming reporter for the New York Post, Page Six and Decider, who regularly covers streaming releases and consumer‑tech news.
The film’s debut adds another literary adaptation to Prime Video’s growing catalog and underscores the influence of social‑media‑driven book communities in shaping streaming content decisions.
