source: Method acting
text: Method acting Method acting is a range of training and rehearsal techniques that seek to encourage sincere and emotionally expressive performances, as formulated by a number of different theatre practitioners, principally in the United States, where it is among the most popular—and controversial—approaches to acting. These techniques are built on the Stanislavski's "system" of the Russian actor and director Konstantin Stanislavski. Though many have contributed to the development of the Method, three teachers are associated with "having set the standard of its success", though each emphasized different aspects of the approach: Lee Strasberg (the psychological aspects), Stella Adler (the sociological aspects), and Sanford Meisner (the behavioral aspects). The approach was first developed when they worked together at the Group Theatre in New York. All three subsequently claimed to be the rightful heirs of Stanislavski's approach. His three major books were "An Actor Prepares", "Building a Character", and "Creating a Role".
