SPOILERS are ahead for the film and book The Idea of You. You've been warned. So, if you've made it past that intro, it's safe to assume that you streamed the Amazon Prime rom-com The Idea of You this weekend. The movie centers around a romance between the 40-year-old Solène and the 24-year-old boy band member Hayes Campbell — and so does the 2017 Robinne Lee novel that it's based on. Film adaptations of books are often different from the source material, and The Idea of You follows suit in that regard. In fact, the film's entire ending is a huge change from how the book concluded.
Long story short: In both the book and the film, Solène and Hayes initially break up. In the book, they stay that way — but, in the film, they reunite five years after breaking up. Robinne Lee, the author of the novel, shared her thoughts on this substantial shift with Entertainment Weekly. She mentioned that she was not involved in the film's production and had not met the director, Michael Showalter. However, her husband was one of the film's producers and kept her informed about the changes made by the director.
