Jack Nicholson absolutely kills it in every role he’s cast in, but he reportedly didn’t think that would be the case if he portrayed Michael Corleone in The Godfather. Apparently, before Al Pacino was cast in the role, Nicholson was offered the part. He turned it down because, as he once said, “I knew The Godfather was going to be a great film, but at that time I believed Indians should play roles written for Indians and Italians should do the same.”
