Continuity mistake: The closeup of the Soda City calendar shows a much heavier coating of spider webs than the previous shot.
Visible crew/equipment: Towards the end of the fairground scene, as Michael and Ellen are walking to the right, and just before the cop tells them one of the stolen bills has been passed to the dress shop, the shadow of the boom microphone is visible across the brick wall in the background.

Continuity mistake: Bela Lugosi offers John Berkes a cigar ("a real Havana"), but when he's relaxing, he calls him by his 'street' name, Fingers. The man nervously brings a hand to his collar, but at the cut Fingers' fingers are gone out of frame. (00:06:30)
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.
