The Giant of Metropolis
In 20,000 B.C. Muscleman Ohro travels to the sinful capital of Atlantis to rebuke its godlessness and hubris and becomes involved in the battle against its evil lord Yohtar and his hideous super-science schemes. There's sword-and-sandal thrills, sci-fi funk, lots of skin, and a wildly sadomasochistic tone that really carries it over the top!
