How about the Space Vampire in Buck Rogers?

I've always loved that particular episode, but his big bulbous head is a bit silly. I met the episode's writer, David Wise, at a convention last year, and he told me his original intent was for the vampire to be something in the romantic vein (haha) of Frank Langella, since the film had recently come out.
