Actors who portray real people in films often mimic their behaviors to better fit the part on screen, or even go on extreme diets to transform their bodies to look like someone else's.
Tom Hanks lost 55 pounds to resemble a stranded plane crash survivor in Cast Away, for example, while Charlize Theron gained 30 pounds to play a prostitute in Monster.
