Hercules vs. Moloch (Italian: Ercole contro Moloch, French: Hercule contre Moloch, also released as Conquest of Mycenae) is a 1963 Italian/French international co-production peplum film written and directed by Giorgio Ferroni and starring Gordon Scott.
Led by a facially deformed King who believes himself Moloch incarnated, the madman demands slaves as tribute, where he tortures and kills a selected few.
Prince Glaucus from Tiryns has an idea to seize and destroy Mycenae from within.
He becomes a gladiator, but he secretly plots to lead a revolution and destroy the creature that has enslaved the people.
