The Million Eyes of Sumuru (1967)

Shirley Eaton stars as the mighty title character in the pulp adventure The Million Eyes of Sumuru (1967), the tagline of which states a mouthful: "She Rules a Palace of Pleasure . . . for Women! Where men are used in a diabolical plot to destroy civilization!" Frankie Avalon and George Nader play a couple of secret agents sent to infiltrate Sumuru's empire, where the bikini-topped, mini-skirted female denizens are so powerful that they can instantly snap a man's neck—using only their thighs. It's all high camp, swingin' '60s fun, with some sexy near nudity from Maria Rohm.
