A style of acting formalised by Konstantin Stanislavsky which is believed by some to create more realistic performances. Essentially, the theory requires actors to draw experiences from their own personal lives that correlate to the character they are playing - an extremely demanding process emotionally. In some cases, "method" actors take the theory even further by arranging events in their private lives to resemble the lives of their characters. See the trivia entries for Down and Out in Beverly Hills and One Flew Over the Cuckoo's Nest for examples, and the trivia entry for Marathon Man for an amusing anecdote.
