He had a small but memorable role in Steven Spielberg's "1941" (1979) in scenes with Toshiro Mifune and Christopher Lee; during one scene, he enumerates the objects on his person, similar to the way he does in the "Survival Kit Contents Check" scene in "Dr. Strangelove". In 1978, Pickens lent his voice to theme park Silver Dollar City as a character named Rube Dugan, for a ride called "Rube Dugan's Diving Bell". The diving bell was a simulation ride that took passengers on a journey to the bottom of Lake Silver and back. The ride was in operation from 1978 to 1984. He also played werewolf sheriff Sam Newfield in "The Howling" (1981).
