A Dynamic Duo
Ben Affleck should credit a lot of his '90s fame to his writing partner and best friend, Matt Damon. They wrote and starred in films like Good Will Hunting in 1997. That film is considered one of their best joint efforts, and Affleck went on to star in films such as Shakespeare In Love, Armageddon, and Pearl Harbor. He and brother Casey Affleck are both still esteemed actors, and Damon remains close as well.
