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)
Other mistake: Before the opening scene, where there is a paragraph setting up the history of the musical, in the third line there is a spelling error: "it's" should be "its" since it is a possessive pronoun and not a contraction.
Other mistake: Handsome and Charming head out of Snakes End (followed by the newlyweds) and begin their long journey. It then cuts to Cactus Jack before he begins the journey, and at the start of this shot as he places Whiskey's bit, we can see the signpost with three wooden arrow signs and the hillside behind him. This is the same location where Cactus Jack lays trap number seven, named "the tunnel in the hillside," on the next day during the journey; noticeable when Handsome and Charming arrive.
