Frequently acted in movies for director Jerry Jameson.
His foul-mouthed, Star Trek (1966) character "Korax" is the first to utter the language, Klingonese (although he distinctly pronounces it "Klingonee"). Fans have attributed the insult in this dialect ("petaQ!") from his last name.

Along with Adam West, Roddy McDowall, Bob Hastings, Barry Dennen, Steve Franken and Judy Strangis, he is one of only seven actors to appear in both Batman (1966) and Batman: The Animated Series (1992).
