Matt Damon in Courage Under Fire

In one of his first big movie roles, the future Jason Bourne decided that if his character was going to be a war-traumatized drug addict, he should look like a war-traumatized drug addict. Damon lost 40 pounds, and seriously damaged his health in the process. Luckily, during that time, Ben Affleck ate for both of them.
Renée Zellweger in Bridget Jones’s Diary

Not only did the petite Chicago star have to pile on the pounds to play zaftig Londoner Jones, the Texas native also had to adopt an English accent. Um…do you mean to tell us there wasn’t a single hefty British actress available when this thing was made? If you spotted us Kate Winslet and the brunette that Hugh Grant chubby-chased in Love Actually we could still come up with at least three more.
Robert De Niro in Raging Bull

Explaining that Robert De Niro gained a massive amount of weight to play washed-up boxer Jake La Motta may not seem like much, but remember, this was slim, Mean Streets De Niro, not Meet the Parents De Niro. Having to pack the equivalent of two Joe Pescis to his waistline was a much bigger deal back then. Nowadays, he gains a Pesci just looking at that cannoli. Why must you tempt him, cannoli? He’s got to look somewhat presentable for Meet the Fockers’ Baby or whatever.
Charlize Theron in Monster

It’s sad that we live in a world where statuesque South African beauties can’t be accepted for who they are, so they have to “ugly up” in order to get any kind of respect from their peers. Charlize was unrecognizable as lesbian serial killer Aileen Wuornos, making it impossible, for once, to fantasize about her. Luckily, the producers of Aeon Flux talked her out of playing the character as a horribly disfigured assassin from the future.
