Factual error: When the real German soldiers are playing 20 questions in the bar, one of the cards shows the name of Genghis Khan. This is an English-language word; as Germans, they would have written Dschingis Khan instead. As the whole scene deals with exposing the British/American spies and subtle differences in their language or behaviour, this is especially unfavorable here.
Question: In the scenes leading up to the shoot-out in the bar, the German Major says that the Captain just gave himself away. I am assuming that he is referring to the fact that the Captain held up three fingers when asking for only three glasses. I don't see how this is a give-away. Can someone please explain?scrappy1982
