Other mistake: Throughout most of the film, Mattie Ross' gun is correctly shown to be a Colt's Dragoon .44 caliber revolver. However, in the scene where Tom Chaney is looking down at her from the top of the well into which she had fallen, the gun in his hand is a Colt's Model 1860 Army. Presumably, when he, too falls into the well after being shot by Marshall Cogburn, the gun goes with him. When Cogburn retrieves the weapon before helping Mattie out of the pit, the gun is once more a Colt's Dragoon.
Revealing mistake: Early in the film Gene Hackman tests a rocket-powered backpack outside the space station. He slowly spins sideways through a complete circle, but instead of each side of his body being lit up in turn as it's pointed towards the sun, the light stays constant throughout the maneuver, showing that the makers just took a photo of Hackman and rotated it.
Continuity mistake: Frankenstein buys a sprig of freesias as a buttonhole: two yellow flowers and a purple. The sprig immediately changes into two purple flowers and a yellow. When Frankenstein meets Mrs Brandt and they go into the drawing room, the flowers are two purples and a red with yellow centre. Once in the cellar to see Mr Brandt, the red goes, and a yellow is back with two purples. (00:57:45 - 01:03:55)
Factual error: Lou Erding qualifies his car (42) in third, yet prior to engine startup, the famous "position pole" shows 42 as starting in 20th.
Other mistake: As Anne is about to be executed for adultery she begins recalling the important events of her life since meeting Henry VIII. She counts each of the wooden stakes numbered "100 Days" and recalls various events involving she and Henry. There should be 10 to account for the 1000 days but there are only nine. (02:13:00)
Continuity mistake: After crashing, the pilot jumps from his burning plane with the back of his jacket on fire. The flames are extinguished but after a short dialogue, the pilot is seen walking from the scene from behind with not even a scorch mark on his jacket.
Visible crew/equipment: Bearded crew-member visible in the scene where Mr. Sugden is selecting the football teams.
Revealing mistake: When the Remagen bridge is bombed, it is obvious that the bomber planes shown have been taken from several shots (possibly also from an earlier film) and the shots were superimposed. Also, the bombers appear transparent, and the background sky's color is unnaturally strong, too.
Continuity mistake: When Carl lets his dog out of the bag, in the close-up there's a shadow on Rod Steiger's boot, and a shadow of something or someone standing between him and the camera: both are gone in the following shot, when the dog runs across the lawn (and 'knocks aside' the camera).

Revealing mistake: Captain Beckman is in the tower shooting at a small German plane that is attacking the castle. He is told to aim for the engine but when he does and shoots it down its not the engine that smokes, its both the wheels that are smoking from some very obvious smoke tubes attached to the fixed landing gear.demodon
