Prime Video Drops Official Trailer for 'The Love Hypothesis' Starring Lili Reinhart
Prime Video has released the official trailer for its film adaptation of Ali Hazelwood's bestselling novel The Love Hypothesis, with Lili Reinhart and Tom Bateman leading the cast. The film streams globally on the platform on 23 September 2026. (The Hollywood Reporter)
The trailer arrived on 26 August, a day after Prime Video teased it on its Facebook page with a short clip promising the full reveal "tomorrow." The project had already surfaced publicly in late June, when Prime Video posted a teaser on its own YouTube channel confirming the September premiere. (YouTube)
Reinhart plays Olive, a Ph.D. candidate in biology who fakes a relationship to convince her best friend she has moved on. Bateman steps in as Adam Carlsen, the intimidating professor who becomes her reluctant fake boyfriend. The setup — science, academia, a pretend romance that turns real — is the engine of Hazelwood's novel, which built a large following after its 2021 publication and helped establish the "STEM romance" subgenre.

Claire Scanlon, whose television directing credits include The Office and Never Have I Ever, directs from a screenplay by Sarah Rothschild. Elizabeth Cantillon produces the film, which is an Amazon MGM Studios release — the label Amazon has used for theatrical and streaming titles following its 2024 acquisition of MGM.

The supporting cast fleshes out the academic world: Rachel Marsh as Ahn, Nicholas Duvernay as Jeremy, plus Jaboukie Young-White and Arty Froushan in roles yet to be detailed in full. (The Hollywood Reporter)
For Hazelwood's readers, this trailer is the first proper look at how the novel's tone translates to screen — the lab-bench banter, the faculty politics, the slow-burn central pairing. For Prime Video, it adds another literary adaptation to a slate that has leaned heavily on established book properties, banking on existing fanbases to drive opening-weekend viewership on the platform.
The Love Hypothesis premieres on Prime Video on 23 September 2026.
