Revealing mistake: While the German officer, played by Hardy Krüger, is in a pill box reporting back to his headquarters, with the bridge seen in the background, rush-hour traffic can been seen on the bridge.
Revealing mistake: As Sean Connery steps on board the aircraft, at the top left two aircraft are shown flying overhead, but backwards, presumably stock footage run that way for some reason. (00:39:20)
Suggested correction: The fighters are not flying backwards. Simple as that.
