Other mistake: Johnny Finger is supposed to be a crack shot, and in his first scene he supposedly beats three guys on the draw simultaneously. However, as he goes for his revolver with his left hand, it goes off almost immediately whilst still pointing straight downwards. (00:02:45)
Other mistake: When the Lone Ranger is on the roof of the train he shoots at Fuller, who is uncoupling the carriages. He looks back at the train and shouts something - at this point the two trains are on a bend and The Lone Ranger is just coming into view, making his shot at Fuller impossible.
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: 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: 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: Moving them to Laredo early in the morning, except it's noon by the wagon shadows.
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 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: John Wayne is recruiting other victims of outlaw violence to assemble his Avengers team; he gives them handwritten notes saying, "Go to Hall's barn at ten o'clock tonight." Forgetting the fact that he somehow managed to find a dozen or more ace gunslingers with his same vengeance agenda in the vicinity of the same barn, it is obvious, looking at the two handwritten notes, that they were in fact written by very different hands, not by just one person. (00:12:50 - 00:13:25)
Other mistake: Brian Keith sneaks into an Indian encampment at night while they are sleeping. In order to stampede their horses, he rapidly fires the one and only six-shooter revolver he has into the air...eight times.
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: 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: 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: 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: The opening credits misspell the name of production supervisor Peter Sczygiol ('Sceygiol') and firearms technician Gino Vagniluca ('Vigniluca').
Other mistake: It's been established Rambo was born 7/6/1947. When we see his driver's license, his DOB is 12/4/1950.
Other mistake: Outlaws are chased by a mounted posse. One outlaw up on a hill shoots two of the posse members from long distance. Next shot, the two injured posse members are lying on stretchers and the chief deputy orders someone to go back to town and get a wagon. The stretchers were canvas, wooden handled, military style. Where did they come from?
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.
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.
