Errores

When Tom, Cap, Orrin, and Tyrel ride into Purgatorie, you can see a large telephone pole with modern transformers on it, in the background over the buildings.

After Tell finds Ange in the cave, and Cap yells up to him to see where he is, Cap's coat disappears between shots.

When Benson Bigelow arrives in the Purgatory saloon and orders whisky, Delilah's off the shoulder blouse changes from one side to the other.

After the dummy gets shot in the jail cell, Tyrel and Orrin run out to catch the shooter. When the camera goes back to the prisoner in the other cell, you can see Tyrel moving around behind him.

When Tyrell first approaches the water hole looking over the top of the hill it is nearly a cloudless day, but when the camera switches back to the same shot, there are large cumulus clouds visible.

During the gunfight, when Tom Selleck shoots the man behind the barrel, he pulls the trigger one more time after dying.

During the gunfight, when the man in the hayloft is shot, even though he is supposed to be dead, his leg is still bent even though it should have straightened out when he died.

Most of the lever action repeating rifles are Model 1892 Winchesters, but the story is set in 1869.

It is obvious the filming was done in Arizona and not New Mexico, seeing saguaro cactus in most outdoor shots.
