Frankenstein’s Monster, Dracula, and the Wolf Man provide three-ply horror display in this chiller-diller meller.
Plot [from a story by Curt Siodmak] takes the usual twists of the suspense-chill series. Boris Karloff is the mad scientist with a penchant for delving into transplanting of brains. He escapes from prison with deformed J. Carrol Naish, takes over a traveling chamber of horror exhibit to release the skeleton of Dracula for brief forays among the populace, and then goes to the ruins of the Frankenstein castle to secure records of former transplanting research.
Karloff is the usual menace in lead role of the scientist, with Naish particularly well cast as the hunchback. Lon Chaney is the Wolf Man, while John Carradine steps into the Dracula assignment.
