- 1. Hera wasn't actually Hercules' mother. While Zeus was his father, his mother was a mortal named Alcmene, which made him a demigod. Hercules was conceived when Zeus disguised himself as Alcmene's husband Amphitryon, who was away to fight in a war. Zeus' wife Hera, furious over her husband's adultery, swore vengeance, and bestowed misfortune over Hercules wherever and whenever she could. In the movie, Alcmene and her husband adopt Baby Hercules.
- 2. The Fates do not share an eye. The Graeae, perpetually old women who helped Perseus find Medusa, shared an eye.
- 3. Pegasus was created by the blood of Medusa, not clouds (as seen in the film) on Olympus.
- 4. Zeus did not bestow the underworld on Hades but the two, along with Poseidon, drew lots.
- 5. In the movie, Hades releases the Titans from a place at the bottom of the ocean, but in the original myth they were banished to Tartarus, which is in the deepest and worst section of the underworld.
- 6. The Cyclops, although brother to the Titans, was not a Titan.
- 7. The Titans say Zeus put them there, but Zeus's grandfather Uranus did. Zeus freed the Cyclops along with Giants and creatures called Hundred-Handed Ones, and he was given the gift of thunder and lightning as a token of appreciation.
- 8. Narcissus is not a Greek God, and therefore would not be on Mount Olympus.
- 9. Megara was Hercules' first wife, with whom he had children; however, Hera induced a fit of rage and madness in him, during which he killed them all. To repent for these sins, Hercules performed all of his heroic deeds (most of them are seen, mentioned or referred to in the movie). It is his later wife Deianara who Hercules saves from the river guardian Nessos; in revenge, Nessos gives Deianara a poisonous shirt, saying it will make Hercules love her more. Unsuspecting, she later gives him the shirt, believing his love for her is waning. The shirt clings to Hercules' skin and causes him agonizing pains. He builds a funeral pyre and sits on top of it, begging his friends to set it on fire and end his misery. No one can bring himself to do it, except for Philoctetes (who was a man and not a satyr). Upon death, Zeus deifies Hercules and admits him onto Olympus.
