During the first season of the 1967-68 sitcom Mothers-in-Law, Carmel played Kaye Ballard's husband; when he demanded more money for his services, he was promptly replaced by Richard Deacon. Busy in the cartoon voiceover field in the 1970s, Carmel was heard as the voice of Smokey the Bear. After several years' inactivity, Roger C. Carmel was found dead in his Hollywood home, the victim of an apparent drug overdose.
