After bad guy Taggert (I. Stanford Jolley) shoots the lights out in the saloon, a scuffle ensues in the dark. However when the newly arrived Judge Walsh (Steve Clark) enters to meet Eddie Dean shortly after, the lighting is just fine.
As Eddie Dean and Ace Banyon (Mikel Conrad) brawl in the saloon, they land on top of the bar before going over it, and you can see the entire bar wobble as they hit it.
