Anthar l'invincibile (Devil of the Desert Against the Son of Hercules) (1964)

One of the runts of this series, but not for lack of trying. It simply doesn't have a script for the action (which are what these early superhero films were about, yah?), and it's Hercules doesn't have the oomph. Women are sold as sex toys, which is all good until one of them happens to be the next Queen of the kingdom. That's when one of the roaming sons of Hercules gets involved to dispense with some asswhupping vengeance.
