Marlon Brando (April 3, 1924 – July 1, 2004) was an American screen and stage actor. He is widely regarded as having had a significant impact on the art of film acting. While he became notorious for his "mumbling" diction and exuding a raw animal magnetism, his mercurial performances were nonetheless highly regarded, and he is widely considered as one of the greatest and most influential actors of the 20th century. Director Martin Scorsese said of him, "He is the marker. There's 'before Brando' and 'after Brando'." Actor Jack Nicholson once said, "When Marlon dies, everybody moves up one."
