Casey Affleck

• Education: George Washington University (attended); Columbia University (attended)

Significance: Casey Affleck has appeared in supporting and major roles in numerous films, and has also written screenplays and directed movies. He won national acclaim for his Academy Award–winning performance in Manchester by the Sea (2016).

Background

Actor and director Caleb Casey McGuire Affleck-Boldt was born on August 12, 1975, in Falmouth, Massachusetts. He grew up in a working-class neighborhood in Cambridge, Massachusetts, where his mother, Christopher Anne (née Boldt) Affleck—also referred to as Christine or Chris—taught elementary school. His father, Timothy Byers Affleck, worked a series of jobs, including as a janitor at Harvard University, bartender, and electrician. His parents divorced when he was young. His older brother is the well-known actor, screenwriter, and director Ben Affleck.

Affleck’s mother was friends with a casting director, and she launched her sons’ acting careers when they were young. Affleck began auditioning when he was five and served as an extra in several films. His television debut was in the American Playhouse production of Lanford Wilson’s play Lemon Sky (1988), in which he played Jerry, the preteen brother of the protagonist, Alan (Kevin Bacon). Two years later, Affleck appeared in the miniseries The Kennedys of Massachusetts as Robert Kennedy in his early teens. Despite Affleck’s early forays into acting, he later credited Gerry Speca, a drama teacher at Cambridge Rindge and Latin School, with teaching him the basics of the craft and inspiring him to pursue a career in acting.

Dramatic Career

After his 1993 high school graduation, Affleck moved to Los Angeles, where he spent his time unsuccessfully auditioning for sitcom roles. Then, childhood friend and fellow actor Matt Damon—who along with Ben was Affleck’s roommate at the time—recommended him for a supporting role in director Gus Van Sant’s New England–based film, To Die For (1995), which featured Nicole Kidman as an ambitious television personality. Affleck landed the part of Russel Hines, a lowlife teenager and friend of Jimmy Emmett, played by Joaquin Phoenix. Affleck’s next role was in the comedy Race the Sun (1996), where he played a high school student in Hawaii who designed a solar-powered car. He was disappointed with his experience on the project and decided to go to college, where he studied politics at George Washington University in Washington, DC. Afflect later transferred to Columbia University, where he studied physics and astronomy on and off between gigs, before leaving school for good.

Affleck was in school when Van Sant persuaded him to take a supporting role in Good Will Hunting (1997), which Ben Affleck and Damon had cowritten and were starring in. That same year, he appeared in Chasing Amy, which also starred his brother. Ben Affleck and Damon won an Oscar for best screenplay for Good Will Hunting, but the film did little to advance Casey’s career. Affleck then acted in a series of supporting roles in less noteworthy films, including Desert Blue (1998), 200 Cigarettes (1999), Committed (2000), and Drowning Mona (2000).

Having briefly lost his enthusiasm for acting, Affleck regained it after he was cast as Virgil Malloy in the 2001 box-office hit Ocean’s Eleven. He reprised the role in Ocean’s Twelve (2004) and Ocean’s Thirteen (2007). After filming Ocean’s Eleven, he appeared with Damon and Summer Phoenix in Kenneth Lonergan’s This Is Our Youth (2002) at the Garrick Theatre in London’s West End. He also tried his hand at writing, cowriting the screenplay for the indie film Gerry (2002) with Damon, in which both actors also starred as characters named Gerry.

Affleck’s breakout year was 2007 when he had two major roles besides his appearance in Ocean’s Thirteen. His performance as Robert Ford in The Assassination of Jesse James by the Coward Robert Ford (2007) won him both a Golden Globe and an Academy Award nomination for best-supporting actor. His portrayal of a Boston-area private detective investigating a young girl's abduction in Gone Baby Gone (2007)—his brother’s directing debut—was also highly praised. Affleck followed these successes with his portrayal of a Texas deputy sheriff turned sadistic murderer in The Killer Inside Me (2010). The pulp erotica film, which featured Jessica Alba and Kate Hudson, incited outrage over its depictions of gratuitous violence toward women, although critics positively reviewed Affleck’s lead role performance.

In 2010, Affleck made his directing debut with I’m Still Here, a mockumentary about his close friend Joaquin Phoenix’s transition from an acting career to one as a rapper, which turned out to be a hoax. He and Phoenix also starred in the film, which received poor reviews and resulted in two women suing Affleck for sexual harassment. Affleck denied the charges, and both women settled their cases out of court.

A string of acting roles followed, including a role in a television documentary and as the voice of a character in the animated feature ParaNorman (2012). In 2016, Affleck played the role of Lee Chandler, an emotionally distraught handyman shaken by a personal tragedy, in the movie Manchester by the Sea. For his portrayal of Chandler, he won several prestigious best-actor awards, including an Oscar, a Golden Globe, and a BAFTA. Affleck’s subsequent movies included The Old Man & the Gun (2018); Light of My Life (2019), which he also wrote and directed; Our Friend (2019); The World to Come (2020); Every Breath You Take (2021); and Dreamin' Wild (2022). In 2023, Affleck appeared in the award-winning biographical drama Oppenheimer, directed by Christopher Nolan. Affleck played US military intelligence officer Boris Pash during the film's interrogation scene against J. Robert Oppenheimer (Cillian Murphy). While he only appeared in a supporting role, Affleck received widespread praise for his Oppenheimer performance.

Impact

Long overshadowed by his more famous brother, Ben, Casey Affleck made his mark as an actor with his performances in The Assassination of Jesse James by the Coward Robert Ford and Gone Baby Gone. His Oscar for best actor for his performance in Manchester by the Sea helped solidify his celebrity status. However, his career was also dogged by controversy; in 2018, he bowed out of a role as an Academy Awards presenter when news of two previously settled lawsuits alleging sexual misconduct resurfaced. In the years that followed, he adopted a notably low public profile, focusing on independent projects and avoiding major press appearances. He also addressed the controversy more directly in interviews, expressing a desire to listen, learn, and support changing industry standards. Rather than pursuing large studio roles, he rebuilt his career through smaller, actor-driven films, often taking on writing, directing, and producing responsibilities. This shift toward quieter, introspective projects contributed to a gradual professional rebound and allowed him to reestablish himself within the industry without returning to traditional celebrity visibility.

Personal Life

Affleck married actress Summer Phoenix in 2006 after several years of dating. The couple had two sons, Indiana and Atticus, before separating in 2015 and finalizing their divorce in 2017. In 2021, Affleck confirmed his relationship with actress Caylee Cowan, and the two remained publicly together, frequently appearing at events and collaborating on independent film projects. In interviews, Affleck referred to Cowan as a significant creative and personal partner.
