Karloff embodies a blind sculptor who gives his figures an astonishingly tragic realism since his pieces actually hide corpses. Via necrophilia, this blind Frankenstein had his castle by the sea on the neo-Moorish battlements of the El Bil-Bil Castle in Benalmádena, which can be visited before arriving at the Nautilus Hotel in Torremolinos, and which, in addition to housing the mythical Hollywood monster, was the setting for some scenes of coastal glamour applauded by Boris Karloff himself.
