Horror icon Boris Karloff stars as a scientist who's simply mad over mutation in the first of two spine-tinglers based on stories by H.P. Lovecraft. In Die, Monster, Die, a man discovers his fiancée's dad (Karloff) is responsible for the rash of deformities. Gidget goes Goth in the next film, in which a sweet librarian (Sandra Dee) falls under the spell of a creepy stranger (Dean Stockwell) who's prowling for a sacrificial lamb.
