Actors Who Went To Extreme Measures For Their Movie Roles

Many actors take their roles seriously to the point where no one knows who the real person behind the role is. Richard Gere is an example of an actor who went above and beyond. In Time Out Of Mind, he wanted to raise awareness for the homeless by working with the Coalition for Homeless and spoke directly with homeless New Yorkers.

Some actors sacrificed more than they should have. From strict diets to unrecognizable costumes and makeup, to taking it so far as putting their lives on the line, some actors are serious about their work. Their drastic changes were either rewarding, or it was a role they should have never taken on.
