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: 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: 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: 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: 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 trajectory of the arrow that hits Mr Peacock in the chest seems impossible.
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: When Bob Hope is singing Buttons and Bows with accordion, to a sleepy Jane Russell, no-one is driving the horses.
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: 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 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: A shootout occurs in a hotel, where a shotgun blast apparently opens the money box. None of the perpetrators fired into the room.
