Herc is up to his usual shenanigans in yet another Italian muscle epic, the third entry in the "Hercules" series that Joseph E. Levine brought to America. Unfortunately, Steve Reeves isn't around, so Hercules is played by Reg Park, who mostly sleepwalks through the role. Seriously, several important plot points rely on Hercules being asleep. And when he's awake, he mostly just throws things and looks confused.
The title is somewhat misleading, since there's only one captive woman and she doesn't figure too much into the plot. Instead, the story concerns Hercules trying to overthrow an evil queen (played by Fay Spain) who is ruling the hidden island of Atlantis. All the Atlanteans worship the god Uranus, leading to plenty of unintentional crude humor in the dialogue.
This one is actually somewhat fun, if you don't think about it too much.
"Uranus has abandoned us!"
This was the first of Park's five films. He did two more as Hercules, and one each as Maciste and Ursus, a couple of Italian Hercules-knock off characters.
