1. 'The Departed'
Leave it to Martin Scorsese to find the perfect part for Wahlberg's unique blend of muted aggression and working-class contempt. With his rat-tat-tat delivery, his incessant ball-busting, his absolute and total suspicion of everybody and everything, Wahlberg nearly walked away with the director's star-studded, Oscar-winning gangster epic. Meet the no-nonsense staff sergeant Dignam, who relishes his pissy interactions with Leonardo DiCaprio's undercover officer Billy Costigan, Alec Baldwin's department go-to guy and anyone else who questions him (asked who he is by an incompetent underling, he shoots back, "I'm the guy who does his job. You must be the other guy."). These foul-mouthed tirades are a perfect fit for the actor. He was nominated for an Oscar for the part; frankly, he deserved to win.
