La noche de los mil gatos (1972)

Millionaire playboy Hugo flies around Acapulco in his private helicopter to pick up sexy young women. He whisks them away to his secluded old castle, where he wines and dines them. With the aid of his bald, mute little helper, Dorgo, he kills his dates, keeping their heads in a crystal cage and feeding their chopped up body parts to his 1,000-strong army of bloodthirsty, flesh hungry cats.
