Continuity mistake: In the scene where Lily is hiding behind Thomas' computer desk, she uses her little Eiffel tower necklace to put inside the socket to short out the power. When she goes to put it in, you can see the computer is plugged in on the bottom socket. After a really quick cut scene, the computer is now plugged in on the top socket. (01:05:00)
Factual error: Colonel Meyer's promotions are listed in his SS ID card as Hauptmann, Oberstleutnant and Oberst. Since the SS used a different ranking system from the Wehrmacht, they should actually be Hauptsturmführer, Obersturmbannführer and Standartenführer.
