“Uncle Harry” was a wolfman, presumably of human birth.
Description[]
Described by his witch niece Phyllis Diller as “always sort of a lone wolf”, the tuxedo-wearing Uncle Harry was also a classical wolfman. It would seem that Harry had died by 1952, as Phyllis spoke of him in the past tense when an image of him appeared on her crystal-ball TV.
Behind the scenes[]
Uncle Harry appears briefly in the 1972 The Mouse Factory episode Spooks and Magic. The Internet Movie Database claims he was portrayed by a certain John Burnside.
