Other mistake: When Schultz meets the Speck Bros. visible breath comes out of the slaves' mouths due to the cold, but not from Schultz or the brothers'.
Other mistake: During the film the narrator states: "He also had a condition that was referred to as "granulated eyelids" and it caused him to blink more than usual as if he found creation slightly more than he could accept." However, this never occurs once in the movie and in fact the opposite happens, Jesse stares into space hardly blinking throughout the entire film.
Other mistake: During the shootout scene, Kevin Costner is firing a single revolver while advancing across a street. He fires at least 10 shots from a six shot revolver without reloading. In just the part of the sequence where he fires multiple shots in rapid sequence into a single guy he fires 7 shots.
Other mistake: In the final gunfight when Joe shoots the gun from Ramon's hands and kills the rest of his gang, he fires six shots. He then shoots the rope that Silvanito has been tied up to without reloading. His gun is a revolver, which only holds six bullets, yet Joe fires seven times.
Other mistake: Moving them to Laredo early in the morning, except it's noon by the wagon shadows.
Other mistake: Richard Benjamin kicks in the door to the hotel room to shoot Yul Brynner, a.k.a. the gunslinger. When the gunslinger falls backwards out of the window his black hat never falls off, it stays on the whole time.
Other mistake: In the attack on the jacales outside the Alamo, a Mexican soldier is shot and crawling on the ground. Crockett asks him his name just as he dies. Later at the Battle of San Jacinto, the same soldier is shown sinking below the surface of Peggy's Lake as a Texican strangles another soldier with his musket.
Other mistake: After the assassination in the outside toilet, as Clint and the kid are riding away they are very close together and being shot at by the other cowboys. The scene ends with the focus on two of the cowboys standing side by side but shooting in directions about 90 degrees apart. At the range they were shooting the targets would have to be 50 metres apart, but were actually last seen side by side.
Other mistake: At the beginning, when Rosie strips down to bathe in the lake, only her skirt comes off, revealing her bare bottom. But not her blouse.
Other mistake: While Ransom Stoddard and his wife are on the train back to Washington, the conductor tells them that the train will be able to maintain a speed of 25 mph throughout the journey. The film is set around 1900, by which time trains were regularly topping 65 mph, and the outside scenery is moving faster than it would for something traveling at 25 mph.
Other mistake: The villain's plan is to impersonate along with his large crew a platoon of the Mexican army. He already captured the soldiers and has them incapacitated, all he needs to do is take their uniforms. Instead of doing so, though, he mows down the whole lot with a heavy machinegun. When it's time to put on the show, everyone wears nice and tidy white uniforms.
Other mistake: The old man is plowing the field in front of Belle's old residence. The little girl picks up the doll. A second before the cut, the girl lifts her eyes from the doll and does not look at her pops, or around; she looks right at the fourth wall and smiles, waiting for her cue. (00:01:50)
Other mistake: Jed has eight rounds on him/in his pistol. He tells Chad to go to his saddlebag to get another round of ammo and keep it in his pocket. Jed tells Chad "Let's play catch the bullet" since Chad (not his marshal dad Britt) is the only MacMasters there. Jed fires six rounds before Britt shows up on top of the hill, then two more (eight rounds). Jed shoots a ninth and tenth round before he tells Chad, "Get that ammo." Chad is never shown giving Jed the ammo from his pocket, but Jed keeps shooting. (01:13:42 - 01:17:46)
Other mistake: Just as the preacher finishes stitching up Jake's wound, a shot rings out from the street, and everyone goes outside to find Percy Dollarhyde drunk and shooting up the town. Percy is right-handed but holsters his 6-shooter revolver on the left, and this appears to be his only sidearm. Even if he did carry another 6-shooter, that wouldn't explain how he fires 13 shots in this scene without reloading.
Other mistake: When Regret, Jake, Pilar and her father are escaping from the Comanchero village, there's a close up of Jake (Wayne) in the back of the wagon shooting a rifle. The scene shows him shooting left-handed. It's a reverse print. Look at his "right" hand in the scene. He has a ring on his "right" hand ring finger. A few moments later, setting the wagon canvas afire trailing out the back of the wagon and shooting right handed, the ring is on his left hand as it is in the rest of the movie.
Other mistake: Just after newlyweds Gil and Lana arrive at Gil's small log cabin, they are visited by a Native American named Blue Back, who brings them a side of venison. Even though it has been pouring rain outside for hours, Blue Back is perfectly dry when he enters the cabin.
Other mistake: A brief section of the film was flipped. One building has a sign saying "FIREARMS" and the lettering is in reverse.
Other mistake: Captain Stanley takes the lid off a small bottle on his right and puts the lid on the desk. He pours a drink and the lid miraculously appears in his left hand. He then screws it on the bottle. Screw top bottles weren't around till 1920. (00:54:50)
Other mistake: The steer horn that penetrates Forrest Tucker near the end of the movie is at right angles to the rest of the steer horn.
Other mistake: In the beginning of the film when the stage coach is approaching Minnie's haberdashery, a well-worn horse path when approaching the haberdashery but it's been snowing a long time, and there is not a lot of traffic going to the haberdashery so this path should not be so worn.
