'The Love Hypothesis' follow-up movies: Will Ali Hazelwood’s book universe continue on screen?

Two other novels from the connected fictional universe are now being developed for the screen

Ali Hazelwood’s The Love Hypothesis may not have a direct sequel movie yet, but two other novels from its connected fictional universe are now being developed for the screen.

Amazon is developing a feature adaptation of Hazelwood’s Love, Theoretically, her 2023 romance novel, according to Deadline.

The project will be written and directed by Sofia Alvarez, with Colleen Hoover, Lauren Levine, Max Siemers and Tanner Anderson producing. Hazelwood is attached as an executive producer.

The connection to The Love Hypothesis is more than simply sharing an author. Love, Theoretically centres on theoretical physicist Elsie Hannaway and experimental physicist Jack Smith. 

Jack is a friend of Adam Carlsen, the male lead played by Tom Bateman in the The Love Hypothesis adaptation. This gives the Amazon project a direct character connection to the original story.

Hazelwood’s Deep End expands those connections further.

Published in 2025, the novel follows Scarlett Vandermeer, a competitive diver, and Lukas Blomqvist, an elite swimmer, as they navigate a college romance.

Deadline reported in August that Netflix had launched development on a feature adaptation, with Laura Kosann writing the screenplay and Shawn Levy and Dan Levine producing through 21 Laps.

Alex Cooper and Matt Kaplan are also producing through Unwell Productions, while Hazelwood will executive produce.

Importantly, Deep End and Love, Theoretically include cameo appearances from Olive Smith and Adam Carlsen.

Their appearances connect the newer romances directly to the couple at the centre of The Love Hypothesis.

The books remain standalone stories, however, the planned adaptations could allow Hazelwood’s interconnected characters and fictional world to continue appearing across different films.

The Love Hypothesis is now streaming on Prime Video
