Continuity mistake: West has a different hairstyle as it is parted down the middle when he is fighting outside the Nugget Saloon. In the inside fight and throughout this episode, there is no part in his hair - with the only exception of this outside fight. (00:13:30)
Continuity mistake: Near the end of the episode when West walks into the mansion where the meeting is behind held, just as he enters, Lt. Armand Renard can be seen talking to Artemus at the bottom of the staircase, but Renard died earlier in the episode. They obviously filmed this scene at the same time as the first scene, but missed that continuity error in the editing. (00:46:40)
Revealing mistake: After West shoots Major Hazard on the water tower, the falling stuntman lands on a safety cushion that is about a half foot below the ground surface. Further, the next scene cut shows Major Hazard being covered by the tower contents, but Hazard is now lying on the ground surface, not below it like the stuntman.
Revealing mistake: The final gun battle in town has a gunman in a tower shooting at West. The gunman's perch is enclosed on all four sides by a bannister, but when West returns fire, shooting the gunman out of the tower, the bannister in front of the gunman has disappeared, allowing the stuntman a clear path to fall out of it.
