Robert Selden Duvall was an American actor, filmmaker, and producer, best known for his roles in films of the later 20th century. Duvall began acting professionally on stage in 1952, performing in summer plays at the Gateway Playhouse in Bellport on Long Island until 1959, with a one-year break while serving in the U.S. Army. In his early theater career, he made contacts that then led to a career on television in the 1960s on shows such as The Defenders, Playhouse 90, and Armstrong Circle Theatre. He made his Broadway debut in the play Wait Until Dark in 1966, and, in 1977, he returned from screen acting to the stage in David Mamet's play American Buffalo, earning a Drama Desk Award for Outstanding Actor in a Play nomination.
