As The Love Hypothesis arrives on Prime Video, one question has become especially important for fans of Ali Hazelwood’s novel: how does the author feel about the screen version?
Lili Reinhart, who stars as Olive Smith, recently said Hazelwood has been showing strong support for the adaptation. That gives the movie’s release a useful author-to-screen connection beyond the usual cast interviews.
Ali Hazelwood approved the casting
PEOPLE reported that Reinhart described Hazelwood’s response to the movie’s casting and direction as enthusiastic. Reinhart said that support was meaningful because Hazelwood created Olive and Adam in the original novel.
Did Ali Hazelwood visit the set?
Hazelwood was not present throughout the original Montreal shoot, according to the PEOPLE interview. Reinhart later met the author during reshoots in Los Angeles.
Who plays Olive and Adam?
Lili Reinhart plays Olive Smith, a Ph.D. candidate whose fake relationship begins after she impulsively kisses professor Adam Carlsen. Tom Bateman plays Adam.
The adaptation is directed by Claire Scanlon and written by Sarah Rothschild.
What does the movie change from the book?
The basic romantic setup remains recognizable: Olive enters a fake relationship with Adam, initially as a way to convince her best friend Ahn that she has moved on from Jeremy. The movie compresses a novel-length story into a feature runtime, so some scenes and supporting-story beats naturally have to be streamlined or rearranged.
That does not mean every change is an author-approved change individually. Hazelwood’s reported support is better understood as a positive response to the overall adaptation and team, rather than a scene-by-scene confirmation of every alteration.
Why the author's reaction matters to book fans
Adaptations often create a gap between what readers imagined and what appears on screen. Hazelwood’s involvement as an executive producer and her positive comments give fans an additional point of context when they compare the film with the 2021 novel.
When can you watch The Love Hypothesis?
The movie streams globally on Prime Video September 23, 2026. Amazon lists it as an adaptation of Hazelwood’s bestselling romance novel.
