Factual error: When the bombs are being taken down the lane, in the background where the lane meets the road a white mini can be seen passing the entrance.
Revealing mistake: When Mr Witt rides out of the Zulu camp in a 2 horse cart at the beginning of the movie, just before it exits, you can see it's a stunt double at the reins.
Continuity mistake: In the train yard scene when Le Biche and Colonel Von Windheim are watching for the trains to switch to the right tracks a pipe is tossed onto a chair and tobacco spills out, but when the camera is panned away and comes back the tobacco is nowhere to be seen.
Factual error: The movie shows a 'jet' aircraft belonging to 'consolidated airlines'. The so called airplane is a laugh. It has two jet engines attached to the horizontal stabilizers. The landing gear appear to be bolted to the wings. During the movie this plane crashes and the engines are moved to a terminal to be examined. They are too small to be real engines. During the course of examining the engines, they are run inside the terminal building. One of the investigators stands 10 feet behind the jet intake and is not sucked inside. The cockpit is not even close to what one would find in a jet airplane.
Factual error: The radio Walter uses on the island has no apparent power source; we never see either batteries or a hand-cranked generator.
Continuity mistake: When Bruno goes to the Captain, to ask for leave so he can go to his daughter's funeral, he places his cap on the desk in front of him. It slips to the floor, but a minute later his cap is magically back on the desk.
Continuity mistake: The three enter a small cantina and start a fight and fire. The place is huge on the inside, with stairs to a second floor. From the outside it's just a small shack.
