If there is one movie book fans have been waiting for a release date on, it’s The Love Hypothesis, based on the novel by Ali Hazelwood. Well, now the date is out!
Prime Video announced the date in the best way possible: a video that capture the heart of the summer romance. However, it’s not coming this summer. Fans will have to wait until the fall, as the official release date is September 23, 2026.
It will head straight to Prime Video. Yes, we would love to see more movies out in theaters, but getting to watch at home with our besties is a lot of fun!
The announcement video starts with someone popping a cup with the numbers “9.23” on a counter and calling the name Olive. Then Lili Reinhart grabs it and takes a sip.

The Love Hypothesis brings the fun fake dating trope to the screen once more, but it’s not for money. Reinhart’s Olive Smith finds out that her best friend has feelings for her ex-boyfriend. The best friend is being a girl’s girl and not acting on those feelings, but this is a case of Olive wanting Anh to find love and romance, so she pretends to date someone else to prove that she’s moved on.
It’s kind of sweet when you think about it, and that’s certainly what captured the hearts of many. However, Olive has to figure out who to pretend to date, as her PhD work is her baby — she’s looking for a cure for cancer. She has to kiss the first man she sees in the hallway to prove she’s dating someone, and that man just happens to be her professor, Dr. Adam Carlsen.
Fortunately for Olive, her professor is willing to help her out with this adventure. He does have his own reasons, and those are financially motivated. His research funds have been frozen as the college is worried he will move to another location, and he thinks having a girlfriend will show that he is settled and committed to staying in place.
Tom Bateman will play Adam, and there’s been plenty of hype around The Love Hypothesis thanks to the way Bateman and Reinhart have taken to social media.
