Continuity mistake: At the start of the train chase Tonto blows the whistle as he passes the bad guy who says "shoot him you idiot". The soldier opens fire with the machine gun and Tonto is suddenly back in front and passing him again. (02:03:35)
Continuity mistake: In the first shot of the dead man hanging form the tree, his head appears to be about 12" from the tree limb. After Mattie climbs up to cut him down, his head is several feet from the tree limb.
Continuity mistake: Hugh's wounds change from when he cuts open the horse to the ending when he is sitting inside the shack. Specifically, a wound on his right shoulder is there and gone between those two sequences. His back wounds also change considerably.
Continuity mistake: When the bad guy winds up to throw the dynamite into the cantina, McNally puts a round through his brisket, and he falls to the ground clutching his belly. He weakly tosses the dynamite, then stumbles back behind the adobe, now clutching his right shoulder.
Continuity mistake: At the beginning, in the scene where Rayne finds two bodies near a small house, she takes out one of her blades. Firstly, she grabs it in a wrong way (the tonfa-like blades should be held under the arm), but when the camera angle changes she holds it properly.
Continuity mistake: A couple of times in the movie, the camera pans to John Wayne, and his hair is parted on the wrong side. (Reverse editing flaw).
Continuity mistake: When Gummer and Black Hand Kelly make an agreement, Kelly looks to his left and he isn't holding a glass. When it cuts, he is looking to his right and holding a glass. (00:40:35)
Continuity mistake: In the gunfight scene in the street between Paden and Cobb the length and angle of the shadows of both characters and the buildings change several times from one shot to the next.
Continuity mistake: When Jesse and Frank are telling the doctor that his son was killed (right in the beginning of the movie) Jesse gained a lot of beard growth in five minutes. When they are outside talking to Zee, he has just a light beard, and then when they go inside he has a heavier one.
Continuity mistake: When Rango was at the mayor's office, the mayor grabs out a jug of water, and he opens the lid. But in the next shot, the lid is sealed again.
Continuity mistake: Many times through out the film the red bag that contains all the money is not seen with the main group, even though they supposedly keep it with them at all times. The most noticeable example is when the two main characters first fly into Spain in the balloon and when the interior of the basket is visible the bag has simply vanished, but they have it again later.
Continuity mistake: When Monco drives away with the dead bandits a tail gate of the cart is swinging freely. A few seconds later - after having retrieved the money bag from the tree and driving away 'into the sunset' - the tail gate is not there. (02:04:35)
Continuity mistake: When Francis Fryer throws the cowboy he loses the scarf in his hand but when the camera angle changes he has it again.
Continuity mistake: When Sharon Stone confronts Gene Hackman at the end, she throws the marshal star at his feet. It is an inch or two in front of his boots. After he is shot, he gets flung backwards several feet. Stone then picks the star up and throws it to Russell Crowe. She picks it up from behind Hackman's body, several feet away from where it landed but still sticking out of the sand the same way.
Continuity mistake: At the end of the movie when Cheyenne is shaving, while Harmonica and Frank are having their shoot-out, he cuts himself at the sound of the gunshots. When Jill tells him that he is a handsome man the cut is gone. (02:22:25)
Continuity mistake: At the start when Mary gets off the buckboard she has a food basket with a couple of things but no cloth/bread, but upon entering the house the basket has a red and white check cloth and bread sticking out.
Continuity mistake: After Evans was shot near the end of the movie, Ben Wade jumped out of the train to look at him. If you look over Wade's shoulder, you will see that Nez (the Apache) had already arrived at his spot, and Campos (the Mexican sharpshooter) threw Wade's gun belt to Charlie Prince. After the movie cut a couple of times, Nez was shown walking up, throwing Wade's gun belt to Campos, who then threw it to Charlie Prince.
Continuity mistake: In the final duel, when Gary Cooper is shot on his left arm, he grabs the spot where he was supposedly wounded with his right hand, then takes off the hand, and we don't see a wound and his shirt is not torn. In the following shot we see both the wound and the tear in the shirt. (01:14:05)
Continuity mistake: When Marlboro Man rides a wheelie next to the motorcycle cop, the bike goes from having wide glide forks to a narrow glide setup.
Continuity mistake: A group of new recruits is introduced to horseriding. One spindly volunteer gallops off first, but when we see him from behind he has been replaced by a stuntman of about twice his width. (00:44:10)
