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.
Factual error: In the climactic charge scenes in which the three ranks of British soldiers deliver volley after volley into the Zulu masses, the soldiers closest to the camera are correctly equipped with lever action Martini-Henry rifles but those further back in the line can be seen pulling up and back on bolt action rifles, wrong for the era.
Factual error: During the scenes with the armored train, a USATC S100 can be seen. This should not be possible as the S100s were American locomotives sent to the Allies during the war and would not have been in France at the time. They only arrived in France after WW2.
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.
