Bad Santa (1994)
He's not fot, he's not round, and he definitely isn't jolly. Billy Bob Thornton's booze-drinking, womanising Santa Claus is hilarious, in a dark comedy sort of way. A strange friend in the form of a socially inept boy called Thurman Merman makes the off-the-rails Santa see the error of his ways after years of drug abuse and robberies. Heartwarming and filthy at the same time.
