In a sense, all actors use Stanislavski’s method, as it is in many ways the rosetta stone of organized acting theory, the touchstone of all later acting techniques and styles. Its founding status makes it the foundation of many styles of acting, particularly the later style of method acting. Some of the most famous and well-known users of Stanislavski’s method are Marlon Brando, Al Pacino, Robert De Niro, Daniel Day-Lewis, and Marilyn Monroe.
