I remember seeing him in an episode of Night Gallery. He played a vampire who came to a funeral director, wanting to stage his funeral. Of course he wouldn’t actually be dead, he just wanted to throw a big party and see all his friends there to “mourn” him. Of course they were of the same creepy ilk as he was. I liked the little touch when he, being VERY insistent with the director on having things his OWN way, gently lifted his upper lip to expose his fangs. He got what he wanted.
