This Is Where I Leave You: 5 Changes the Movie Made From the Book

In the book, there's more of a simmering resentment from Paul (Corey Stoll) toward his little brother Judd (Jason Bateman). In a heartbreaking flashback sequence, we learn that back in high school, Paul defended his little brother against a bully, and for his effort, he was attacked by a Rottweiler who shredded his throwing arm, ending his burgeoning football career. In the movie, there's no sad tale, just a little bit of weirdness between them since Judd had dated Paul's now-wife.
