Just found another one - "Superstition, fear, and jealousy" at the beginning of "Dragula" comes from Horror Hotel (1960) and is spoken by none other than Christopher Lee. The previous post from a month ago was when I discovered that the yelping scream at the end of "Electric Head Pt. 1 - The Agony" comes from a rather nasty scene towards the end of Henry: Portrait of a Serial Killer (1986) courtesy of Tom Towles (who also played arch-douche Harry Cooper in the 1990 remake of Night of the Living Dead)
