Revealing mistake: The waterfront set always features a blue, cloud-dotted sky, even when the streets are wet from supposed rain. And the clouds are static, never moving or changing, betraying the fact that they're part of a backdrop.
Continuity mistake: Conchita slaps Cash across the left cheek, which he's rubbing as he returns to his office. In the next shot, as he comes through the door, he's rubbing his right cheek instead.
Visible crew/equipment: When Cable closes the cabinet, the boom shadow can be seen moving on the wall behind him. (00:04:20)
Continuity mistake: When Cash joins Sarah in the carriage, she's holding her suitcase and a kerchief in her lap. She removes the cloth and lets him take the bag. But when the shot cuts to a wider angle, she does this again and he takes the bag from her a second time. (00:34:00)
Continuity mistake: The drawings on the chalk boards in the old schoolhouse keep changing between shots. (00:41:00)
Continuity mistake: Garrison begins destroying the schoolhouse/saloon walls with an axe, knocking over a whiskey bottle on the bar. When he overturns the bookshelf, the bottle has disappeared. (00:42:30)
Continuity mistake: The window Cable is peeking through closes itself between shots. (00:45:00)
Continuity mistake: When Cash uncovers the gold, the bricks change configuration several times between takes. (00:47:15)
Factual error: Cable refers throughout the episode to "The Civil War." This term was not in use until well after the era in which the series is set. It was known at the time as "The War Between the States," or, in the South, "The War of Northern Aggression."
