Goofs

When we first see Bill Meceita (John Phillip Law), he is practicing his shooting. The first revolver he shoots, a six-shot Colt Peacemaker, turns out to be a 9 shooter, and the second is an 11 shooter.

After the bank robbery, Ryan is dumped by the bandits on the road the next morning to be captured. The following scene returns to the night of the robbery. The Sheriff is making his initial inquiries when Ryan is delivered to him as a prisoner.

During the card game between Cavanaugh & Meceita, Cavanaugh shows his hand "4 aces" with the cards being in As, Ah, Ac, Ad, Js order. Right before the third strike on the piano a quick shot shows the cards are now in an Js, Ah, Ac, Ad, As order.

When Bill talks to the girl in the inn, before the bandits arrive, the long shot shows her face in shadows. When it goes to a closer shot, her right eye is highlighted by sunlight.

When the bad guys charge the village after the fire is gone, there are lot more than there were before. Also, the same people fall off their horses in identical scenes right after each other.

The couplings visible on the trains are European and not American ones.

In one shot of an "outdoor" conversation between Ryan and Bill, Ryan casts a shadow on the background mountain range, revealing that the shot was on a soundstage in front of a painted backdrop.

When Bill swaps out one pistol for another during his target practice early in the film, the sound of the gun against the wooden table is noticeably delayed (only playing while he's holstering his next gun).

At about 49 minutes when Meceita demands the piano player to hit three notes, the notes heard in the soundtrack are all C but the first key that the piano player presses is a C, the second D, and the third are both C and D together.

The fate of the villagers is not shown.

When Bill Meceita has a shootout with one of the villains, he sticks out his hat on a stick and has the villain shoot at the hat. When he reveals himself, he says "Before you fire, remember the Meceita ranch." Then they draw their pistols and Bill kills him. However, the villain had his gun already in his hand to shoot at the hat. There is no shot showing him holstering his gun, nor would it make sense for him to do so.

The armed villagers are all atop the front wall, but a bandit is able to ride up to the front gate and throw dynamite at the blockade.

At about 38 minutes the barman is thrown out of window and when he re-enters the saloon he is shot, after which he falls into the street. He is then seen being thrown out of the bar a second time almost immediately afterwards.
