Hercules in the Underworld (1994) on Netflix

Plot summary

Hercules lives as a family man with his wife Deianeira, their children Aeson, Clonus and Ilea, and the centaur Nessus. The ground splits open in the village of Gryphon, and vapor from the fissure kills two men. Elsewhere, a trickster lures fighters against a false Eryx the Boxer; Hercules answers the call and defeats the giant, then wrecks Hera's temple after she refuses him a truce. Iole, a young woman from Gryphon, comes for help and faints. Drunk, Nessus tells Deianeira that Hercules cannot resist Iole, and a woman at a market recognizes the necklace Iole gave her as the token of Neurian maidens trained in seduction. Deianeira rides after Hercules to warn him, and he and Iole travel on toward Gryphon.
