Marlon Brando, for all his accolades, was known throughout his career to be something of an asshole. The legendary film actor, especially in his later years, is said to have consistently demanded insane provisions on set, slapping huge cue cards to actors' foreheads, and defying production conventions so flippantly that major studio heads vowed to never again work with him. And yet, he is still known as one of Hollywood's greatest all-time actors.
