One of the most critically acclaimed actors in Hollywood, Robert De Niro is well-known for pursuing "method acting" to its fullest extent. De Niro has taken home the Oscar twice -- for 1974's The Godfather II and for 1980's Raging Bull. With so many films to his credit, De Niro has not always guaranteed success at the box office, but he has certainly portrayed some of the most memorable characters in movie history.
