スタニスラフスキー・システム
From 1958, Corbett began to appear regularly in films, coming to public attention as a serious, intense performer, in contrast to his later reputation in sitcom. He appeared in television dramas such as "The Adventures of Robin Hood" (as four characters in episodes between 1957 and 1960) and "Police Surgeon" (1960). He also worked and studied Stanislavski's system at Joan Littlewood's Theatre Workshop at the Theatre Royal in Stratford, London.
