Method acting
Boleslawski acted in "Love One Another" ("Die Gezeichneten", 1922), a German silent film directed by Danish director Carl Theodor Dreyer. In September 1922, he made his way to New York City, where, now known as "Richard Boleslawski" (the English spelling of his name), he began to teach Stanislavski's 'system' (which, in the US, developed into Method acting) with fellow émigré Maria Ouspenskaya. In 1923, he founded the American Laboratory Theatre in New York. Among his students were Lee Strasberg, Stella Adler and Harold Clurman, who were all founding members of the Group Theatre (1931–1940), the first American acting ensemble to utilize Stanislavski's techniques.
