BookTok’s favorite fake dating romance is officially making its way to the screen.
After becoming one of the biggest romance novels of the past few years, Ali Hazelwood’s The Love Hypothesis is getting the movie adaptation fans have been waiting for. Prime Video has officially announced that the film will premiere on September 23rd, bringing Olive and Adam’s beloved story to audiences around the world.
From the first trailer to the confirmed cast, here’s everything we know so far about The Love Hypothesis movie.
The Love Hypothesis Release Date
Prime Video has confirmed that The Love Hypothesis will premiere exclusively on September 23.
With the release just a couple of months away, excitement is already building among readers eager to see one of BookTok’s favorite romances come to life.
Watch the Official Trailer
Prime Video has also released the film’s first official trailer—and if you’re anything like me, it will probably make you want to pick up the book immediately (or read it all over again).
Watch the trailer here:
The trailer offers our first look at Olive and Adam’s fake dating relationship, giving fans a glimpse of the humor, chemistry, and academic setting that made the novel such a hit.
What Is The Love Hypothesis About?
If you haven’t read the novel yet, The Love Hypothesis follows Olive Smith, a third-year Ph.D. candidate at Stanford University.
Desperate to convince her best friend that she’s moved on from a previous relationship, Olive impulsively kisses the first man she sees.
Unfortunately…
That man happens to be Dr. Adam Carlsen—a notoriously intimidating professor with a reputation for being brilliant, demanding, and completely unapproachable.
Rather than exposing Olive’s lie, Adam surprisingly agrees to continue the fake relationship.
As the two spend more time together, what starts as pretend slowly turns into something much more real.
Why Readers Fell in Love with the Book
Since its release, The Love Hypothesis has become one of BookTok’s biggest success stories.
The novel combines several fan-favorite romance tropes, including:
- 💕 Fake dating
- ☀️ Grumpy x Sunshine
- 🎓 Academic romance
- 🔬 STEM setting
- ❤️ Slow-burn romance
What also helps the novel stand out is its setting.
Instead of centering around a small town or workplace romance, Hazelwood places the story within the competitive world of graduate school and scientific research at Stanford University.
The novel explores the realities of life in academia while also touching on topics like sexism in STEM, imposter syndrome, and the challenges many women face while pursuing scientific careers.
That combination of humor, romance, and heartfelt moments helped turn the novel into a New York Times bestseller and one of the defining romance books of the BookTok era.
Meet the Cast
Prime Video has assembled an exciting cast to bring the beloved characters to life.
Olive Smith
Lili Reinhart
Known for her role as Betty Cooper in Riverdale, Reinhart takes on the role of Olive Smith, an ambitious Ph.D. candidate whose fake relationship changes everything.
Dr. Adam Carlsen
Tom Bateman
Tom Bateman will portray the mysterious and intimidating Dr. Adam Carlsen, one of the most beloved book boyfriends in modern romance.
Fans have already begun debating whether Bateman perfectly matches the version of Adam they imagined while reading the novel—but we’ll have to wait until September to find out.
Ahn
Rachel Marsh
Rachel Marsh joins the cast as Ahn, Olive’s supportive best friend and one of the story’s most lovable side characters.
Who’s Behind the Movie?
The adaptation is directed by Claire Scanlon, whose previous work includes romantic comedies and television favorites like Set It Up, Brooklyn Nine-Nine, and The Good Place.
Given Scanlon’s experience balancing humor with heartfelt character moments, she seems like a natural fit for adapting Hazelwood’s witty romance.
My Biggest Hope for the Adaptation
One thing I’m especially hoping the movie captures is the chemistry between Olive and Adam.
The fake dating trope only works if you genuinely believe these two characters belong together—and that’s one of the biggest reasons readers fell in love with the novel.
I’m also excited to see how the film brings the academic setting to life.
The world of graduate school and scientific research feels refreshingly different from most romantic comedies, and it’s one of the things that makes The Love Hypothesis stand out.
Final Thoughts
With an incredible cast, a charming trailer, and one of BookTok’s most beloved romance novels as its source material, The Love Hypothesis is already shaping up to be one of this fall’s most anticipated book-to-screen adaptations.
I’ll definitely be reading the book before September 23—and I’ll be back after the movie premieres with a full Book vs. Screen comparison, Was It Better? review, and breakdown of the biggest changes from the novel.
Until then, I’ll be counting down the days.
