Born on August 12, 1975, Casey Affleck is an Academy Award and Golden Globe-nominated actor, who is also known as the younger brother of actor Ben Affleck. He is the son of Chris Ann, a school district teacher, and Timothy Affleck, a drug counselor and former actor with the Theater Company of Boston.
Casey Affleck attended George Washington University before transferring to Columbia University in New York City, where he majored in physics, astronomy, and Western philosophy.
Upon getting attracted to the glitz and glamour of Hollywood, Affleck landed his first movie role, a sociopath teenager in Gus Van Sant's 1995 dark comedy To Die For, alongside Joaquin Phoenix and Nicole Kidman. He was then cast in Race the Sun alongside Halle Berry and though this movie turned out to be a box office flop, he bounced back in the silver screen with two films featuring his older brother Ben in Chasing Amy and Good Will Hunting, which was a major hit that jump-started the careers of Matt Damon and the Affleck brothers.
Following a string of movies that performed poorly at the box office and with critics, Casey Affleck turned his attention to screenwriting, teaming up with Matt Damon to write the 2002 film Gerry, which is about two friends who get lost while hiking in the desert. On the other hand, he never really left the canvas as he starred in the film The Last Kiss as a friend of Zach Braff's character and made a cameo in the Joaquin Phoenix-directed video Tired of Being Sorry for Balthazar Getty's band Ringside.
At present, Casey Affleck is married to Summer Phoenix, his girlfriend of six years. The couple has two sons together, Indiana August, who was born on May 31, 2004 in Amsterdam, and Atticus, who was born January 12, 2008.
