Factual error: The events in the film take place in mid-1929, as evidenced by the first Academy Awards being presented in May. However, Wyatt Earp went to the happy hunting grounds in January of that year.
Factual error: Aphrodite mentions Medusa as her friend at point. She was a Gorgon, a monster, killed by Perseus, not a friend to any of the Greek gods.
Suggested correction: That's just the most popular version of the ancient myth. But because the story is based on a myth, and not real events, the story can change. This would be like pointing out a factual error for a film changing the origin story of a comic book character. In the poet Ovid's (47 BC - 17 AD) telling of the story, Medusa was a beautiful young woman who later was turned into an ugly woman with snakes for hair by Athena after Poseidon's actions.
Factual error: The closing credits give thanks to "FAO Schwartz", misspelling the name of the famous toy store with an extra "T".
Factual error: The Los Angeles cops pursuing Lulu, Peaches, and Darlene in Mexico couldn't arrest them due to this being a foreign country where they wouldn't have jurisdiction.
