Elvira's Movie Macabre - Season 1 Episode 5 The Dunwich Horror

Once upon a time, twins were born. One looks and acts human, the other is a many-headed creepy crawly. The human brother wants to bring ""the old ones"" from another dimension. He needs a book called the Necromicon and a human sacrifice. He picks Sandra Dee. ""Hey, look at me, I`m Sandra..."" Oops! Heh heh, wrong movie. Anyway, the creepy-crawly gets out and starts eating all the townspeople. That`ll drive down property values, I can tell ya. Based on H P Lovecraft story.
