Corrected entry: The whole plot turns on the police not finding $250,000 with the dead man on the train. We find out that that money came from an auction of all the materials in the Paris apartment. But then very shortly it turns out that there is another $250,000 that all the former spies are looking for, the $250,000 they stole during the war as spies. Eventually, that money "turns up" as the stamps. But no one ever seems to be concerned about the other $250,000 from the apartment auction. It seems that it was introduced only so that the $250,000 number could surface in the dialogue, then was conveniently forgotten. Where the hell did that money go?
Corrected entry: The lights on the Seine tour boat go out, but in the long shot they are still working.
Corrected entry: The man at the night club that begins the "no hands" game speaks in French and then translates to English. At one point he counts "one, two, three" but speaks in Italian this time: "uno, due, tre."
