Matt Damon turns 39 today — he shares a b-day with a certain mother of two, Happy Birthday Lisa! — and to celebrate we're taking a look back at his impressive career. Even before earning his Oscar for Good Will Hunting Matt has been one our favorite actors in Hollywood. Whether he's with his adorable family, living up to his reputation as one of the nicest guys in Hollywood, making us laugh or making us swoon, Matt is one of a kind. Through it all he's remained gracious, down-to-earth and, of course, he makes an incredibly handsome A-List leading man.
