I didn't know about IMDb until I watched this movie and wanted to know more about it. I will try not to be repetitive and focus on some details others may have also been astounded at. When the American and the girl showed up at the plane, somehow he was just hanging around the plane in broad daylight, when the place was crawling with German guards who must have been trained at the same place the guards in the Holy Grail were trained (remember those idiots- "Unless he has to leave". Then she showed up in a car full of Germans dressed as a nurse (she was a B- movie actress in the film). How did we get from the previous scene to this one, did she sleep with one of the idiot guards "so we just stay here until we have to leave". Then Ron Perlman (evil German) tells the nurse he will kill her when the plane lands. Then he says "damn" later when she exits through an open window in the unguarded first floor room in the château. Somehow the American gets the plane's engine to stop and force land on an airfield that just happens to have the three Russian paratroopers arriving at the same time to ambush the Germans with perfectly coordinated timing, impossible mate. Then the American tells the Russian to shoot him in the forehead "you've never killed a man have you?" The Russian was handpicked for this most important mission, he must have killed hundreds to be in an elite to be considered as one of three for the mission. The American had earlier called them "trained killers" It goes on and on, just wanted to add my five cents.
