New today Continuity mistake: Midway through this episode as West is ascending the outside wooden steps to Moriarty's office, his shirt has a vertical rip in his upper left chest area. Once West goes inside, that rip is no longer there but is replaced by a much larger vertical rip (much lower from his waist up to his chest). This larger rip is seen throughout this scene. When West leaves Moriarty's office, the larger rip is no longer there and the original smaller higher rip re-appears. In the following scene when West is changing his shirt, the smaller upper rip has been replaced by the much larger lower vertical rip.
New today Continuity mistake: As the boxing match moves from inside to outdoors, West's shirt is drenched on the back, as well as around the collar and top front of the shirt. Outdoors, those areas are dry. When the fight moves by the water, West shirt is torn on his front left (length from the 2nd to 4th buttons). At the end of that scene, that tear no longer shows, but a new one appears much higher (length from 1st to 2nd buttons) and is closer to his arm in the upper left chest area.
New today Continuity mistake: Before the title appears for this episode, in a long screen shot, West is knocked out face-up with both arms extended above his head; only his left elbow is touching the knocked out bad guy next to him. The next immediate close-up shot of West shows West with only his right arm extended above his head and his body is much closer next to the bad guy. As the title appears, West is face-down resting on his right arm when he starts to regain consciousness.
New this month 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.
Visible crew/equipment: The arm of the actual carriage driver is visible poking through the back of the carriage, slapping the horse and signaling it when to stop/proceed with a second set of reins, showing the actor in the carriage was not controlling the horse at all.
Factual error: At the mint, Arte hides in a broom closet. He carries nothing in (nor did he hide anything in there beforehand), yet he emerges later in an "old man" disguise, wearing a wig, hat, mustache, false nose, glasses and janitor costume. Magic closet?
