Barnabas and Willie, the conflicted, often-shirtless werewolf Chris Jennings, and David Collins, the young heir to the family fortune and ghostly doings.
He sometimes had a female companion for adventures, but he never longed for them; they were playmates, nothing more. Instead, David found his strongest emotional bonds with older men, first Chris Jennings, then Quinten (who had a Dorian Gray portrait in the attic), and then unwitting antichrist Jeb Hawkes. I didn't know it then, but I saw some strong gay symbolism in David.
In fact, by the time I moved to West Hollywood, he had retired from acting, and moved to Panama, where today he runs a chain of upscale restaurants.
There have been remakes in 1991, 20015, and 2012, but they eliminated the gay symbolism by casting David with little kids: Joseph Gordon-Levitt, Alexander Gould (top photo), and Gulliver McGrath.
Or maybe it's too late for the magic to return.
