Frankenstein's Castle Of Freaks (1974) Dick Randall

Brazzi plays mad Dr. Frankenstein, Dunn is an evil dwarf and Lugosi (no relation to Bela) is a Neanderthal man. Add a monster named Hulk, and some nude women for sexploitation value. 

This is a mishmash of old Universal horror cliches done up European style by the notorious Dick Randall, who is known for marrying Jayne Mansfield and producing a string of wildly eccentric exploitation films mostly in Europe. This movie has a horny dwarf, a Neanderthal man in feather boots played an actor calling himself Boris Lugosi(!) and a Frankenstein monster who looks like Bozo the Clown. And it's always fun for fans of Eurotrash cinema to spot regulars like Gordon Mitchell and Luciano Pigozzi giving it their all. This Gothic goofiness should satisfy all fans of 70s Eurohorror.
