Continuity mistake: When they've opened the chest, Leslie pays Heyes $1500 in cash, which he's holding in his hand when the gang of robbers gallops up. In the next shot, Heyes turns and raises his hands, and the cash he was holding has disappeared. (00:31:40)
Continuity mistake: Having borrowed the valuable uncut stones from Soapy, Heyes and Curry don't seem able to keep a very good accounting of them. Ten are sent out for evaluation, and twenty-one more are used to salt the fake diamond field. They should be returning thirty-one nuggets to Soapy at the end of the con game. Yet there are fewer than twenty diamonds on the table when Soapy empties the cloth bag. (00:49:50)
Return to Devil's Hole - S1-E7
Continuity mistake: Heyes takes Clara's handbag and dumps its contents on the table. A bundled stack of bills at least an inch thick falls out. Several shots later, though, the pile of money is much thinner, about half its original size. (00:08:25 - 00:10:10)
The Legacy of Charlie O'Rourke - S1-E15
Continuity mistake: While Heyes and Curry talk to Charlie in his cell, Curry's hands change positions on the bars every time the camera angle reverses. (00:04:45)
Continuity mistake: The rifle Curry slings to his saddle when he sets off after Jake disappears during his journey, then reappears just in time for him to use it in getting the drop on Jake. (00:42:40 - 00:44:25)
Continuity mistake: During the scene in the gentleman's club, Grace makes an instant costume change. When she's inside the club room, she has on a white lace dress and hat. When she and Heyes walk the drunk Sylvester out into the hall, she's wearing a bright red dress instead. (00:12:30 - 00:13:20)
Continuity mistake: When the bad guys rough up Heyes, his hair is disarrayed. But when the shot cuts, it's neatly combed again. (00:13:00)
Continuity mistake: When Heyes and Curry, on horseback, are arguing with Joe, the rifle in Joe's hand shifts orientation each time the camera angle reverses. It's pointing up, then down, then up again. (00:38:00)
Continuity mistake: In the opening scenes of the chase, Heyes is wearing a vest, then not wearing a vest, then wearing a vest.
