Biography: William Devane, born on September 5, 1940 in Albany, New York (although some sources indicate he was actually born in 1937) is an American film and television actor.
Perhaps most widely recognized for his ten years as villainous Greg Sumner on the drama series Knots Landing, and his role as President Kennedy in the TV film The Missiles of October, he has also appeared in such films as:
McCabe & Mrs. Miller (1971)
Family Plot (1976)
Marathon Man (1976)
The Bad News Bears in Breaking Training (1977)
In 2005, Devane joined the cast of 24 as Secretary of Defense James Heller, in the show's fourth season. During the middle of the season, however, Devane was one of several cast members to be written out of the series. He returned for one more episode later that season.
