William Henry Duke, Jr. (born February 26, 1943) is an American actor, director, producer, and writer of film and television. Known for his physically imposing frame, Duke's work frequently dwells within the action and crime drama genres but also appears in comedy. Frequently a character actor, he has starred opposite Arnold Schwarzenegger in Commando and Predator, and has appeared in films like American Gigolo, No Man's Land, Bird on a Wire, Menace II Society, Payback, and X-Men: The Last Stand; often plays characters related to law enforcement. As a director, he has helmed episodes of numerous acclaimed and well-known television series including Cagney & Lacey, Hill Street Blues, The Twilight Zone, and American Playhouse, and the crime film Deep Cover and A Rage in Harlem, for which he was nominated for a Palme d'Or. Duke was born in Poughkeepsie, New York, the son of Ethel Louise (née Douglas) and William Henry Duke Sr. After studying at New York University's Tisch School of Arts and the AFI Conservatory, he appeared on Broadway in the 1971 Melvin Van Peebles musical Ain't Supposed to Die a Natural Death. He directed episodes of several noteworthy 1980s television series, including Hill Street Blues and Miami Vice. Standing an imposing 6 ft 4½ in and featuring a closely shaved head, Duke first became a familiar face to moviegoers in Car Wash (1976) where he portrayed fierce young Black Muslim revolutionary Abdullah Mohammed Akbar (formerly known as Duane), and expanded his repertoire with American Gigolo (1980) where he played a gay pimp. As the action-film-oriented genre became more popular, Duke's presence was perfect to portray a string of "tough guy" roles. He notably worked opposite Arnold Schwarzenegger in both Commando and Predator, followed by a role as a police chief in the 1988 Carl Weathers vehicle Action Jackson. Duke appeared uncredited as a DEA officer in The Limey (1999), as well as a police chief opposite Steven Seagal in Exit Wounds. He played a detective investigating a murder in Menace II Society, in which he delivered the often-quoted line, "You done fucked up, you know that, don't you?". He played a corrupt law enforcement agent in two films opposite Mel Gibson - Bird on a Wire (as an FBI agent) and Payback (as a police detective). Duke appears in X-Men: The Last Stand as Trask, Washington in National Security, Levar in Get Rich or Die Tryin' and Nokes in Bad Country.
