Acting in the 20th cent. has been greatly influenced by the theories of the Russian director Constantin Stanislavsky. An advocate of ensemble playing, he believed that an actor must strive for absolute psychological identification with the character being portrayed and that this identification is at least as important as mastery of voice projection or body movement. Stanislavsky's theories were popularized in the United States by the Group Theatre and later by Lee Strasberg at the Actors' Studio, which produced a generation of extremely naturalistic actors, notably Marlon Brando. The emergence of motion pictures and television has offered unprecedented opportunities and challenges for actors, the sensitivity of camera and microphone making subtlety of voice, expression, and movement absolutely essential.
