Continuity mistake: When Mother and Mameha are waiting for the bid on Sayuri's mizuage, Mother's cigarette is short at one point, but becomes longer in the next shot.
Continuity mistake: When Joan first meets with her captains in Orleans, they argue. She walks away and La Hire calls her "a helluva woman". As she walks away, you can see him looking at her. Immediately, she turns back, and he is now looking at the other captains as she walks up to him and belts him. He must have turned his head very quickly, too quickly to be caught on film.
Continuity mistake: When Jack and Mrs. Pendrake meet in the whorehouse and talk through a screen of glass beads, Jack is standing very close to the screen, that's why it's out of focus when the camera is on her "looking through his eyes". However, in one shot it's not, and that looks quite strange because Jack hasn't moved away from the screen. (01:46:35)
Continuity mistake: The city railroad scenes were filmed in Spain, and many of the forest railroad scenes were filmed in Finland; in both of those countries, most of the railroad track is broad gauge (the rails are more than 5 feet apart). The plains and mountains railroad scenes were largely shot in Canada, where the rails are "standard gauge": 4' 8 & 1/2" apart. The rails can be seen to jump between far apart and closer together more than once as the movie progresses.
Continuity mistake: When Gunny Highway first introduces himself to his recon team, he walks into their barracks building. This building was at the end of a row of barracks. Minutes later, when Highway walks out the back end of this building, he actually comes out of a different building further up the street.
Continuity mistake: When the protagonists are trying to get to the French embassy they pass a VW beetle whose windshield is smashed by a Red Khmer. The camera angle is not very helpful but if you look closely you see that the window is gone already, and the pieces flying over the hood are from the bit of glass that sticks in the frame. (00:56:50)
Continuity mistake: In the scene when the aeroplanes have the dogfight, the German plane is in fact a Spitfire and the two British planes are in fact two Messerschmidt 109's. In the making of the film in Spain, they needed one German and two British planes for the scene, so the only way they could do it was to put British markings on the two Spanish Airforce Me 109's, which they had more of than Spitfires.
Continuity mistake: Shortly before the big cattle drive arc begins, Kipling Flynn pours a teacup full of rum for Lady Ashley to drink. The camera cuts to an over-the-shoulder view as Lady Ashley starts to tip back her teacup; at this point, you can see that the cup is completely empty.
Continuity mistake: In the beginning when Topper is about to fight, he puts a red bandana around his head. As he is walking to the fight, one of the flaps of the bandana is draped over his shoulder. The shot changes when he gets to the fight, and both flaps are now behind his shoulders.
Continuity mistake: When Sergeant Major sounds the wake up call in Connor's hut, the Sergeant Major's lanyard (the rope on his uniform) is on his right shoulder. But in the next scene when he is ranting at Patrick Mower and the lads, the lanyard is on his left shoulder.
Continuity mistake: When Marco is in the library searching the internet for information about the scientist, he isn't wearing headphones. Then he notices the security camera recording him, and in the next shot, from the camera's POV, he's wearing them. When it cuts back to 'our' regular view they're gone again immediately, and he puts them on to listen to the computer.
Continuity mistake: The commandos are in the river, at night and they are setting the charges on the bridge, the variety show is going on at the same time. Between the British soldiers heads and the roof of the auditorium, the Japanese soldiers are standing in bright sunlight.
