Other mistake: When Jimmy Stewart talks to George Kennedy about the taking of his son as prisoner. Right after they look at the map. Look over the shoulder of Kennedy in next few frames. You can see a white vehicle move across the horizon under the mountains. Looks like a white van or truck. With a HD TV, you can even see the dust trail as the vehicle moves left across screen.Steve9083
Other mistake: After being torpedoed, John Wayne orders Burke to radio Pearl Harbor. Burke asks "And break radio silence?" to which Wayne sarcastically replies "don't you think the Japanese know our position?" Actually, a submerged WWII sub could not transmit (radio) without surfacing. Having run up on the submerged sub by chance, only the sub knew their position at that moment. Breaking radio silence did in fact give their position away to the Japanese command.
Other mistake: When Ryan arrives at the camp he observes a funeral taking place yet when he goes to meet the camp Commandant he asks what they are celebrating outside.
Other mistake: In various scenes during the movie, a stretcher with the dead body of Stevens is being carried around the prison. There is obviously nothing on the stretcher but a blanket. There is no body, whether actor, dummy or other, just a blanket over an empty stretcher.
