Method acting, known as the Method, is a range of rehearsal techniques, as formulated by a number of different theatre practitioners, that seeks to encourage sincere and expressive performances through identifying with, understanding, and experiencing a character's inner motivation and emotions. These techniques are built on Stanislavski's system, developed by the Russian actor and director Konstantin Stanislavski and captured in his books An Actor Prepares, Building a Character, and Creating a Role.
Marlon Brando's performance in Elia Kazan's film of A Streetcar Named Desire exemplifies the power of Stanislavski-based acting in cinema.
