Factual error: Right before Elvira is burned at the stake, the officer pronouncing judgement on her says "By the power vested in me, by the sovereign state of Massachusetts..."

Although the internal governments appear to be different, they have the same legal status as states within the United States. (01:17:50)

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 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.
