Factual error: Irena, the central character of Cat People, says she is of Serbian ancestry, and that her ancestors fought the Mamluks for their national freedom. Serbia was part of the Islamic Ottoman Empire between the fifteenth and nineteenth centuries. The Mamluks were a military caste who ruled Egypt between 1250 and 1517. To say the Serbs fought the Mamluks for freedom would be comparable to saying that the USA fought the Vikings for independence in 1776.
Factual error: Those in America, mainly in Massachusetts, weren't burned at the stake when accused of witchcraft. They were hanged. It was those in Europe who were burned at the stake.
