6. Adrien Brody
Adrien Brody is one of those actors you probably wouldn't ever associate with method acting, and that's primarily because he doesn't bang on about and romanticise it like a lot of other performers do. Brody ended up snagging the Academy Award for Best Actor for his stirring performance in Roman Polanski's 2002 Best Picture-winning The Pianist. To prepare for the role, of a man living in the war-torn Warsaw ghettos, he decided to sell his apartment and his car in order to allow him to identify better with the person he was playing, a noble and gruelling move, if only because dealing with estate agents usually proves more painful than most of the sacrifices made on this list. Furthermore, in his underwhelming 2005 thriller The Jacket, he spent hours a day on set locked in a straight-jacket, and insisted to be placed inside a morgue cabinet, as reflects several scenes in the film.
