Griffin Dunne

Thomas Griffin Dunne was born on June 8, 1955, in New York City. He is the oldest child of Ellen Beatriz (née Griffin) and Dominick Dunne. His father was born and raised in an Irish Catholic family, while his maternal grandfather was Irish-American and his maternal grandmother was from Sonora, Mexico. He is the older brother of Alexander and Dominique Dunne. His mother founded the victims' rights organization Justice for Homicide Victims after Dominique's murder in 1982. His father was a journalist, producer, writer, and actor. He is also a nephew of writers John Gregory Dunne and Joan Didion. Raised in Los Angeles, Dunne attended the Fay School in Southborough, Massachusetts, and Fountain Valley School in Colorado Springs, where he developed an interest in acting, appearing in many school plays. He was scheduled to perform in a school production of Othello when, on the eve of a performance, a teacher found him smoking marijuana. Dunne was subsequently expelled, and moved back to New York to pursue his acting interests. He studied acting at the Neighborhood Playhouse School of the Theatre under Sanford Meisner.
