Prime Video has released the first teaser trailer for its upcoming adaptation of Ali Hazelwood's popular novel, "The Love Hypothesis." The trailer offers a glimpse into the campus-based romantic comedy starring Lili Reinhart and Tom Bateman.
Reinhart portrays Olive, a Ph.D. student navigating the world of academia. The plot kicks into gear when Olive realizes her best friend, Ahn (Rachel Marsh), has a crush on Jeremy (Nicholas Duvernay), who Olive herself is interested in. To convince Ahn she has moved on, Olive enters into a fake relationship with the widely disliked professor Adam Carlsen, played by Bateman.
The one-minute teaser adopts the style of a retro scientific instructional video, complete with sound effects of film reels and discussions of chemical reactions. A key moment in the trailer features Olive kissing Adam to deter Ahn, then quickly apologizing to the professor, whom she refers to as "Dr. Evil."
The ruse continues as Olive attempts to assure Ahn that her relationship with Carlsen is genuine, responding to Ahn's suggestion of therapy by stating, "No, like a human man."
Later, the trailer shows Adam initiating a kiss with Olive, explaining that her friends are watching. This marks the second kiss featured in the short teaser.
The adaptation also teases the "bridal lift" scene, a fan-favorite from the novel. This moment was previously hinted at in 2025 when Reinhart shared a TikTok video of Bateman lifting her with one arm, which garnered significant online attention.
"The Love Hypothesis" is written by Sarah Rothschild and directed by Claire Scanlon, known for her work on "Set It Up." The film also features Jaboukie Young-White and Arty Froushan in its cast.
The movie is scheduled to be released on Prime Video on September 23. Subscriptions to Prime Video are available through Amazon Prime, which offers a 30-day free trial.
