While it started with Blake Lively's behavior with journalists, now she and director/actor Justin Baldoni are involved in a number of lawsuits surrounding the project (which is streaming with a Netflix subscription).

The lawsuit alleges that "well into production, Lively had not even read the book" the movie is based on, by Colleen Hoover

Colleen Hoover, the author of the book that inspired the 2024 film It Ends With Us, was dragged into the $400 million legal battle between the film’s star, Blake Lively, and director, Justin Baldoni.
