Robert Dean Stockwell (born March 5, 1936 in Los Angeles, California) is an American actor.
He started out as a child star, playing Colin Craven in the 1949 film adaptation of The Secret Garden and the title characters of The Boy with Green Hair and the 1950 film adaptation of Kim. As an adult, he's probably best known on TV as Admiral Al Calavicci on Quantum Leap and Brother John Cavil in Battlestar Galactica (2003), and in film for David Lynch's Dune and Blue Velvet where he memorably lip-synched to Roy Orbison's "In Dreams".
His older brother Guy Stockwell (1933-2002) was also an actor, and their father Harry Stockwell (1902-1984) was the voice of the Prince in Snow White and the Seven Dwarfs.
