Blood of Dracula's Castle is a 1969 horror film with John Carradine. Dracula and his wife now live in the Arizona desert. John Carradine is their loyal butler in charge of providing fresh blood. There's also a werewolf. The music is downright annoying. The whole film -what I saw of it, anyway- is downright annoying. Is it supposed to be a comedy? Hard to tell.
