Other mistake: At the beginning when the lawman is cutting down Eastwood from tree in the background you can see a white vehicle driving along a road in the background.
Other mistake: During the big chase scene, a car hits a camera right after it passes a blue '68 GTO.
Other mistake: When Oliver is meeting Fagin and his boys, he says, "Is this a laundry then, sir?" You can see Jack Wild (Dodger) mouthing that line on the left side of the screen.
Other mistake: In the scene where Burton and Eastwood are in the radio room, two grenades are thrown, which blow the main radio room door off the hinges and Burton and Eastwood run behind the small door and hide in that room. The German soldiers then run up and one of them throws another grenade supposedly into the radio room. However, the actor in his attempt to throw the grenade into the room instead throws the grenade into the door and it bounces back into the hallway in which he is standing and lands in front of him, yet no one reacts to this and seconds later we see an explosion as if the grenade had actually gone into the room, but it is really on the floor in front of the door and would have certainly blown the German soldiers to bits.
Other mistake: After one of Col. Kirby's soldiers has been killed he takes the dead soldier's M-16 and smashes it against a tree. Instead of a magazine the rifle has a plastic sound box, because the 'rifle' is really a toy made by Mattel.
Other mistake: When Jill tries to leave Sweetwater in the morning after Cheyenne's visit, she runs into Harmonica. He has a very nasty, coarsely stitched injury in his cheek that is not accounted for, and for which there was no time to be received, stitched, and the stitches removed again. (Special Edition DVD has a deleted scene in which Harmonica is beaten up, which explains the injury, but it is a continuity mistake within the regular movie.) (01:12:25)
Other mistake: In the opening credits, the copyright year is shown as MCMXLVII (Roman numerals for 1947), when it should be MCMLXVII (1967).
Other mistake: When Walt Coogan is chasing James Ringerman on their motorcycles up the stairs, a funny slip up occurs. Ringerman makes it up OK, and Coogan follows him, only to ride headlong into the corner of the stone staircase. He is just beginning to fall over when Director Don Siegel cuts away to the next scene.
Other mistake: The German subtitles translate Brittany as Britannien (Britain), not as Bretagne. (01:04:00)
Other mistake: Guy goes to the closet and gets Hutch's coat as he's about to leave after having coffee with Rosemary. If you look at her she looks ghostly as they applied more makeup to her face between shots. Unfortunately they missed some spots around her eyes and on her forehead. (01:06:50)
Other mistake: The bank robbers only took old notes, but the lead detective on the case reads out how much money was stolen: "Two million, six hundred and sixty-seven thousand, five hundred and twenty-seven dollars and sixty-two cents." There wasn't any change, it was all notes.
Other mistake: Taylor believes he is on a planet 300 light-years from earth for most of the movie. However, after spending months there, he would have seen the moon at night a number of times, letting him know where he really was before seeing the Statue of Liberty.
Suggested correction: Not necessarily; any astronaut knows that many, many planets have moons, so Taylor could have easily thought that it was simply an odd coincidence that the "other" planet's moon closely resembled Earth's moon.
Other mistake: When Bp. Lakota is being interviewed by George Faber when he is just off the plane from Russia, he responds to a question by addressing Faber by name, Mr. Faber. It is extremely unlikely that Lakota could have known Faber's name beforehand.
Other mistake: 3/4 day mission to the North Pole, no-one grows a millimetre of stubble or has anything to eat.
Other mistake: Mrs. Petrie, Dr. Flemming's secretary, makes two phone calls to Joan Hudson. She dials seven numbers for the first call but only six numbers for the second call.
