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: John Elder whacks Curley (George Kennedy) across the face very hard with an axe handle as Curley was trying to drown the undertaker. Despite this, Curley never shows any mark at all in the subsequent scenes.
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: 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: When the old man was resuscitating the unconscious boy he kept his arm sticking up in the air. His arm should have been besides his body, limp and unmoving.
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: When Paris gets to prison he has a wad of money on him. Before he got that far the court would have taken the money away and given it back to the guy he stole it from.
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: The trajectory of the arrow that hits Mr Peacock in the chest seems impossible.
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: 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: 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: 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: 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: A shootout occurs in a hotel, where a shotgun blast apparently opens the money box. None of the perpetrators fired into the room.
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)
