It Ends with Us: Book vs. Movie
Justin Baldoni’s It Ends with Us (2024) adapts Colleen Hoover’s 2016 novel. Lily Bloom’s relationship with a surgeon forces her to confront patterns of abuse. It Starts with Us continues her story but is not the film’s source.
From Books Adapted
How much of the book it covers
The movie covers the first book; there is a sequel
It Ends with Us adapts Hoover's first book through its ending. It Starts with Us continues the story afterward, alternating between Lily's and Atlas' points of view. Despite its title, it is the sequel, not a prequel.
The 2024 movie does not adapt that second book.
What changed from the book
Lily and Ryle are older in the movie
The movie makes the adult characters older than they are in the book. Screenwriter Christy Hall said she proposed the change early in her conversations with Hoover. Ryle's work as a neurosurgeon was one reason: his training would take years.
Hall also wanted to avoid suggesting that Lily's difficulty leaving an abusive relationship came from being young. She wanted an older Lily whose childhood experiences still affected her. Hoover was involved as Hall developed the screenplay, including the changes Hall thought the movie needed.

The movie leaves out the co-parenting ending
Lily leaves Ryle in both versions. In the book, they agree to co-parent their daughter. The movie removes that arrangement. When Lily later meets Atlas again, she describes her life with her daughter as just the two of them.
An earlier screenplay included Ryle dropping off their child. Director Justin Baldoni said he cut that scene because the movie had too little time to explain how co-parenting could work after the abuse. His version ends Ryle's part in the story after the hospital scene with Lily and their baby.
