If I'm intimidated, I shouldn't be directing a movie. I gotta treat 'em as characters, not as stars. It's hard to not treat Marlon Brando as a legend, a star, it's difficult not to treat Robert De Niro as a star, but that had to go away very fast after I knew them, because I had to work with them. I'm the director, I'm the boss. They're looking to me for guidance.
