In 1993, when two young, unknown actors named Matt Damon and Ben Affleck couldn't get the movie parts they wanted, the lifelong friends decided to write their own screenplay. To their surprise, "Good Will Hunting" - a story about a blue-collar math whiz - became a box office hit after it premiered in 1997. It won an Oscar for Best Original Screenplay, and Matt became one of the hottest young actors in Hollywood. In the years since "Good Will Hunting", Matt has become an A-list actor, starring in many memorable films such as "Saving Private Ryan" and "The Talented Mr. Ripley". One of his most successful roles is that of amnesiac assassin Jason Bourne, who has featured in a trilogy of films beginning with "The Bourne Identity" in 2002. Matt likes to keep his personal life private. However, he doesn't hesitate to use his celebrity to help others. Among the groups he supports are the ONE Campaign and H2O Africa Foundation, which are charitable organizations working to improve living conditions in Africa.
