Chapter 27: Jared Leto
When it comes to physical transformations for his roles, Leto always goes all out. Leto gained 67 pounds for his role as John Lennon’s killer, Mark David Chapman, in Chapter 27. It wasn’t easy for Leto to put on so much weight, and he felt the effects of it physically. The gout Leto developed by the conclusion of filming made it so he couldn’t even walk to the set. Even though it made him sick, Leto said that playing Chapman that way was the only way to get into his head and heart.
