Five Dolls for an August Moon (1970, Mario Bava)

An island murder mystery, so soon before Glass Onion comes out. Good lighting and fashion, the camera getting up in everyone’s business with help of a zoom lens, music going as big as possible… poor acting and dialogue and logic and dubbing.

The Professor has a secret formula, three other guys want him to sell it to them, then everybody starts turning up dead and being sent to the meat locker. The Professor (who also played a professor in Devil Fish) dies, of course, his widow Trudy scheming with Bad Hair Jack, then they shoot each other over the precious microfilm. I lost track of how the island-prowling loner girl was related to anyone else – played by the daughter who hung out with dangerous hippies in A Lizard in a Woman’s Skin – but she survives and gets all the money.
