Continuity mistake: At the end of the film when all the women are dressed up after making clothes out of tablecloths, you can see the Italian woman riding in the front of the wagon. The shot changes and she's riding on the side looking at all the men and smiling. The shot changes again and she's back to the front.
Continuity mistake: At the detective agency, while Bud and Lou are talking to the murderer, the description of the murderer comes over the police radio, and it states "5 feet 11 inches, weighs 165, blue eyes, brown hair, last seen wearing a felt hat and dark borwn overcoat". Then 15 seconds later Bud says out loud, writing on a piece of paper the description "5 feet 10 inches, weight 165, blue eyes, sandy hair".
Continuity mistake: When Charlie Allnut grabs a bottle of gin from the box, all the bottles in it are wrapped with paper for transport. But when Rose Sayer takes the bottles out of the box to empty them into the river, the paper is gone (from the movements of her hand/wrist, you can tell that she doesn't unwrap the paper from the bottles).
Continuity mistake: In the scene where Guy enters Bruno's house to kill his father, Guy takes out a flashlight to look at Bruno's map. In one shot, you can only see the map, and the light is very small and circular, but in a wider shot of Guy's upper torso, the light covers most all of the map.
Continuity mistake: In the early scene in the officers' club, the money in the center of the poker table disappears and reappears with the change of angle.
Continuity mistake: During combat a pilot is shown to be wounded in his right leg. As he is coming in to land, two further shots of him in the cockpit now show him to be wounded in his left leg. Some blood stain patterns on his gear, also the position of his helmet chin strap, also change position from left to right.
Continuity mistake: Early on in the film Alec Guinness is travelling in the back of a van transporting gold bars to the bank. He spots what he believes is a suspicious car following and asks the driver to stop to check it out. The next shot shows the van stopping outside a row of buildings in a London street. The driver gets out to let Alec Guinness out of the van and they are now parked by a low wall with an open vista (probably one of the many bomb sites in London at the time) and no buildings.The next shot then shows the van outside the buildings again.
Continuity mistake: When Jerry gets in Milo's car so that she can get cash to pay him for his paintings, they get into a dark green car. In the next shot they get out of a light (slightly greenish) blue car. (00:23:00)
Continuity mistake: When the Sutherland engages the four French ships, her masts are shot to doll rags, with the upper masts and fighting tops plunging to the deck. However, the lower shrouds and ratlines, which are attached to the tops, remain intact.
