Stella Adler, an actress and acting teacher whose students included Marlon Brando, Warren Beatty, and Robert De Niro, also broke with Strasberg after she studied with Stanislavski. Her version of the method is based on the idea that actors should stimulate emotional experience by imagining the scene's "given circumstances", rather than recalling experiences from their own lives. Adler's approach also seeks to stimulate the actor's imagination through the use of "as ifs", which substitute more personally affecting imagined situations for the circumstances experienced by the character.
