Early Life and Background

Casey Affleck was born on August 12, 1975, in Falmouth, Massachusetts, to Timothy Byers Affleck and Christine Anne Boldt. His father worked a series of jobs, including auto mechanic, carpenter, electrician, bartender, and janitor at Harvard University, and had previously worked as a stage manager, director, writer, and actor with the Theater Company of Boston in the mid-1960s. His mother was a Radcliffe College- and Harvard-educated elementary school teacher. Affleck’s surname is of Scottish origin, and he also has Irish, German, English, and Swedish ancestry.

Affleck’s parents divorced when he was nine, after which he and his older brother, Ben, lived with their mother in Cambridge, Massachusetts, and visited their father weekly. During his childhood he began acting by reenacting what was happening at home during role-play exercises at Alateen meetings. Growing up in a politically active, liberal household in Central Square, Cambridge, he and his brother were regularly taken to the theater by their mother and encouraged to make their own home movies. The brothers sometimes appeared in local weather commercials and worked as film extras because of their mother’s friendship with a local casting director.

Affleck acted in numerous high school theater productions while a student at Cambridge Rindge and Latin School, where his theater teacher, Gerry Speca, helped spark his interest in acting as a profession. At age eighteen he moved to Los Angeles for a year to pursue acting, living with his brother and their childhood friend Matt Damon. He later enrolled at George Washington University to study politics, then transferred to Columbia University in New York City, where he followed the Core Curriculum for two years without graduating.

Path to Acting

Affleck’s earliest professional work came through childhood television, including the 1988 PBS television film Lemon Sky, directed by Jan Egleson, and a role as a young Robert F. Kennedy in the 1990 ABC miniseries The Kennedys of Massachusetts. While these early experiences meant little more than a day off from school at the time, they laid the foundation for a career that would begin in earnest after his move to Los Angeles at eighteen.

His first film role as an adult was as a sociopathic teenager in Gus Van Sant’s 1995 satirical comedy To Die For, where he shared an apartment with co-star Joaquin Phoenix and became close friends with him. While studying at Columbia, he had a supporting role in Van Sant’s Good Will Hunting (1997), written by his brother Ben Affleck and Matt Damon, and improvised many of his lines. He followed this with small roles in films including Chasing Amy (1997), 200 Cigarettes (1999), Drowning Mona (2000), Hamlet (2000), and Finding Forrester (2000), the last of which he also served as Van Sant’s assistant and technical consultant.

He found a measure of commercial success when cast in Steven Soderbergh’s heist comedy Ocean’s Eleven (2001), playing one of two Mormon brothers and wisecracking mechanics alongside Scott Caan. He reprised the role in Ocean’s Twelve (2004) and Ocean’s Thirteen (2007). In 2002 he and Damon starred in Van Sant’s experimental drama Gerry, which they co-wrote, and he appeared with Damon and then-girlfriend Summer Phoenix in a West End stage production of Kenneth Lonergan’s This Is Our Youth, beginning a long creative friendship with Lonergan.
