Continuity: In the saloon, McCabe plays cards and Sheeran lights the lamp while they talk to each other about the bottle of whiskey price. At one point McCabe is shown, from behind, taking the cigar out of his mouth with his left hand and, subsequently, shown from the front, holding the cigar in his mouth with his right hand.
Crew or equipment visible: At 1:41:38 into the film, when McCabe is hiding in the door of the hardware store, a leg and a foot of a crew-member are visible reflected in the window on the left. After the cutaway it is even clearer when the person moves.
Continuity: When the young man in the tall hat is leaving, he hugs each of the girls in turn. In the shot from the front, he the one girl and Ida Coyle is stepping up for her hug. The shot changes to the view from the left, where the hug of the first girl is repeated and Ida Coyle again steps forward.
Miscellaneous: The steam engine was deployable very shortly after the fire was discovered, which would have been possible only if the engine had already been lit.
