Continuity mistake: In the sequence entitled "Their State flag. The spirit of the South". When Ben Cameron enters the room and picks up his little sister, he is wearing his saber. When he then carries her across the room and shows her the flag, his saber is missing. (00:28:30)
Continuity mistake: During the desert chase sequence, when our hero is run off the road by Ernest B. his missing arm is momentarily transposed when he steps from the jeep.
Continuity mistake: In the penultimate scene when Susan has just gotten off the train and is running to Ned Trent, you see her fall over flat on her face and then sit up. Cut to the close up where Ned has also fallen over, Susan is flat on her face again. (01:36:00)
Continuity mistake: When Passepartout and Fogg arrive at The Royal Academy of Science explaining about breaking the speed barrier, Lord Kelvin asks where his authorization is and mocks Fogg while laughing and lowering his right arm. When it cuts, his arm is back up to his stomach. (00:13:00)
Continuity mistake: When Blondie abandons Tuco in the desert, watch the rope around Tuco's neck. It changes between shots, sometimes over his left shoulder, and sometimes hanging down in front of him. It is not due to the camera angle.
Continuity mistake: In the scene where they ride to the top of a hill on horseback, you can see a white van and power lines in the distance.
Continuity mistake: When Morgan is shot while playing pool he is placed on the pool table. An overhead shot shows a wide pool of blood spreading from his right side. In a subsequent shot the pool of blood is much narrower and a completely different shape.
Continuity mistake: After Jack's second horse never comes back, neither do Ben's shoes. Were they with the horse that we don't know what happened to?
Suggested correction: The shoes are purposely removed and never seen again, as is the horse, by Jack. This is mentioned by the Indian tracking them.
Continuity mistake: During the conversation between Jesse James and Charley Ford after James has killed Ed Miller and woke Charley in the middle of the night, Charley's right suspender is initially twisted, yet, in the next shot his suspender is flat against his body, and remains so for the rest of the sequence.
Continuity mistake: When Luz is talking to Jet on the phone for the first time, from the front she's fiddling with the phone cord with her left hand. When it cuts to the reverse, however, her hand is flat on the desk.
Continuity mistake: When Levoi and Crowhorse visit Grandpa for the first time note the white and black beaded belt on the table behind Grandpa. In the beginning it hangs at the edge just at the first black stripe. Just after Grandpa trades Levoi for his glasses and hands him the rock, the belt now hangs nearly to the second black stripe. After that cut the belt now hangs in its original position. (00:37:30 - 00:38:30)
Continuity mistake: When Paris has his private meeting with Woodward, he's smoking a cigar and you can see smoke rising all around him. The camera angle changes to a wide shot and all of the cigar smoke is gone.
Continuity mistake: In the scene where John Wayne is looking down at the arrow that Look has left, his moccasin is all brown. In the next shot, his moccasin is partially opened on the side, revealing his sock.
Continuity mistake: In the trailer, there is a scene showing Matt Damon in a fight. The other person pulls out a knife and cuts Damon on the right side of his face, leaving a big scar. In the next scene of the same commercial the scar changes from the right side of his face to the left side and then back again.
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 third time we see the stagecoach on its way to Denver, it's passing the exact same tree and hill that it passed at the start of its journey. It's also traveling on a paved road, which in 1860s frontier Colorado is extremely unlikely. (00:11:15)
Continuity mistake: Sacajawea (Donna Reed) dives into the water to retrieve some important maps, which have fallen in and been taken to the back of the boat. When she dives in, the maps are back to the original area they fell into, when they should have been quite a distance from where they landed in the water.
Continuity mistake: Near the end, Sam Clayton is nearing the finish. The audio leads you to believe that the horse is breathing VERY hard, but when the camera shows the horse, the nostrils are NOT flared as they would be on a horse that has been run to exhaustion (or even down the block). Also, the people filming this scene obviously have no clue about the nature of sweating in horses. They showed "lather" all through the horse's mane. The ONLY places horses will lather while sweating is where something is rubbing, i.e. underneath the saddle, the bridle or breast collar, where the reins rub on the neck or between their back legs.
Continuity mistake: When the stagecoach enters Tonto street, it's shadow switches sides between angles.
Continuity mistake: When Abbott and Costello are on the train. Costello walks over to see the guys playing poker. In the background a man closes the back door of the train. As Costello passes you see the door is open again and the same guy closes it again. (00:17:10)
