Continuity mistake: The first time Leslie visits Heyes and Curry in jail, they are in two cells right next to one another, Curry lying on a bunk in the cell to the left. The second time she visits to break them out, they are still in two cells next to one another, but the cell with the bunk is on the far left, Curry is the in middle cell, and Heyes is in the cell on the right. When Leslie points her gun at the lock of Heyes's cell door, he takes cover behind Curry, who is suddenly in the same cell with him with no bars between them. When Leslie brings Heyes the letter spike to use in picking the lock, the two are back in different cells with no bunk visible.
Continuity mistake: Heyes is shot from the right and falls from his horse, grazed on the right side of the head. When he's recovering, however, the wound has moved to the left side of his head. (00:13:00)
Revealing mistake: Sam, the third victim, is shot and killed while driving his wagon out of town. We see a long shot of him riding away, then we hear the rifle firing. But the camera lingers a bit too long after that - just enough for us to see the wagon continuing on its way, with a perfectly healthy Sam still at the reins. (00:16:40)
Visible crew/equipment: Curry emerges from the pond into bright sunlight, and the distinctive shadow of the camera is visible against his white shirt. (00:20:20)
Factual error: The dresser mirror in the saloon girl's boudoir is ringed with photos - but they're 20th Century color Polaroids. (00:24:00)
Visible crew/equipment: When the sheriff and his deputy knock on Rachel's door and she opens it, the glass shows us a studio reflector and some of the camera crew. (00:39:30)
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)
Journey from San Juan - S1-E13
Continuity mistake: Curry kisses Michelle outside her hotel room. When the camera angle is on him, his right hand is on her shoulder. When it switches to her, his hand is instantly down at her waist. (00:15:10)
Never Trust an Honest Man - S1-E14
Revealing mistake: In one of the early panoramic shots of the train heading toward the mountains, there are two jet contrails in the sky at the upper right of the screen. (00:07:00)
Never Trust an Honest Man - S1-E14
Continuity mistake: Curry's shaving cream is smeared over his upper lip. Then it isn't. Then it is again. (00:10:40)
Never Trust an Honest Man - S1-E14
Continuity mistake: The part in Mr. Harlingen's hair changes sides several times while he's examining the jewels with his son. (00:25:00)
Never Trust an Honest Man - S1-E14
Revealing mistake: At the end, when Christine's father enters the kitchen, the unmistakable outline of a papered-over electrical outlet is showing on the wall behind him. (00:45:10)
Never Trust an Honest Man - S1-E14
Factual error: For a man of the cloth, the Preacher is remarkably ignorant of one of the best-known passages of the Bible. He says that the 6th Commandment is "thou shalt not steal" and the 8th "thou shalt not kill." It's the other way around.
Never Trust an Honest Man - S1-E14
Character mistake: When Heyes and Curry join the poker game with Harlenjen near the start of the episode, Harlenjen says, "Heyes bets," even though it looks like the other guy is betting first, plus he doesn't know Heyes' real name.
Suggested correction: He said "Ace bets", meaning the high card showing on the table places the first bet. The guy replied "Ace bets a hundred."
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)
The Legacy of Charlie O'Rourke - S1-E15
Revealing mistake: Alice is supposedly playing the guitar while she sings to Charlie in the jail cell. But while her fingers are moving, they aren't forming proper chords on the instrument's strings, nor does her strumming match the music we hear. (00:17:00)
The Legacy of Charlie O'Rourke - S1-E15
Continuity mistake: Curry's string tie disappears when he and Heyes knock on Alice's hotel room door. It's back a few shots later. (00:19:50 - 00:21:00)
The Legacy of Charlie O'Rourke - S1-E15
Continuity mistake: Charlie tells Alice that he buried the gold near the Mexican border. But when she looks up the location on a map, the map she's holding is of the state of Wyoming (which is nowhere near Mexico). When they go after the gold, however, they're in Joshua Tree Forest, Arizona, which is near the border. (00:23:15)
The Legacy of Charlie O'Rourke - S1-E15
Revealing mistake: When Heyes and Curry send the empty stagecoach off to mislead the posse, the road has several 20th Century tire tracks running across it. (00:29:00)
The Legacy of Charlie O'Rourke - S1-E15
Factual error: When Alice, Heyes and Curry dig up the gold bars, they realistically have to use both hands to lift each one. But Heyes then fills two cloth bags with six bars each, hefts the sacks easily and slings them over his saddle. Conservatively, each of those bags would weigh 180 lbs. - he's just tossed the equivalent weight of two full-grown men over his shoulder onto the horse.
