Six Strangers at Apache Springs - S2-E7
Character mistake: Preacher quotes from the bible ("The harvest is past, the summer is ended, and we are not saved") stating it's from Jeremiah chapter 9, verse 20, but she quoted Jeremiah chapter 8, verse 20.
The Strange Fate of Conrad Meyer Zulick - S3-E9
Other mistake: When Doc Donovan reads the wanted posters, the physical description of Heyes mentions dark brown hair and brown eyes, which fits Pete Duel. However, by this episode, Roger Davis had taken over the role. He has light brown hair and blue eyes.
Continuity mistake: Grace says she's going to Laredo. But when the stagecoach reaches its destination and she gets out, the driver says they're in El Paso. (00:41:20 - 00:43:00)
Wrong Train to Brimstone - S1-E4
Factual error: When the train is fully boarded, the conductor waves a lamp to signal the engineer. It's supposed to be 8 pm at night, but it's suspiciously sunny on the platform - and the signal lamp is noticeably not lit. (00:08:45)
The Men That Corrupted Hadleyburg - S2-E18
Continuity mistake: In the opening shot, Heyes and Curry sit outside the Bannerman office pretending to read a copy of the Denver Post. In full shot, they're holding/hiding behind a single unfolded paper. When we cut to a tighter two-shot, though, each of them holds a separate newspaper. (00:02:00)
Something to Get Hung About - S2-E6
Visible crew/equipment: After the street brawl, Heyes, Curry and Stokely walk away arm-in-arm and pass a man in a 20th Century short-sleeved blue shirt with a very 20th Century haircut, leaning on a piece of equipment to the right of the screen - apparently one of the film crew.
Alias Smith and Jones (90 min.) - S1-E1
Continuity mistake: When Harker rouses a sleepy Heyes and drags him to the saloon, Heyes' hair is falling over his forehead. The shot cuts, and his hair is combed back. Then he steps through the curtain to talk to Wheat, and the hair is over his forehead again. (00:46:50 - 00:47:30)
The Posse That Wouldn't Quit - S2-E5
Factual error: Heyes gives Bridget a glowing and accurate description of Denver's Brown Palace Hotel - a landmark that wasn't built until 1892, ten years after the setting here.
Continuity mistake: Curry takes his boots off and runs across a patch of very dusty, dirty desert. When he returns to put his boots back on, the white socks are perfectly clean with no dirt on them.
Plot hole: Though they often had to race off leaving everything behind, and never carried more than two small saddlebags and a thin blanket roll on their horses, Heyes and Curry somehow always had the same heavy winter coats to wear, and the same dress hats and suits to change into whenever needed. Ben Murphy called this phenomenon "our magic saddlebags."
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 Clementine Ingredient - S3-E4
Factual error: Clem puts the paper photo into an envelope and licks the flap to seal it. Pre-cut, pre-gummed envelopes, though they'd been invented, were big-city luxuries rare-to-non-existent in the "wild" west - they were too expensive for most people (like Clem) to afford, especially in the economically depressed decades following the Civil War. You generally cut and folded your own envelopes and glued or sealing-waxed them shut. (00:33:40)
Dreadful Sorry, Clementine - S2-E10
Continuity mistake: It's said here that Gorman took care of Heyes and Curry together when they were both 16. But in "High Lonesome Country," Heyes and Curry discuss being two years apart in age. Their wanted posters list Heyes as 29 and Curry as 27.
Continuity mistake: Heyes and Curry both lose their hats when they jump from the riverboat into the water and swim ashore. There's no time to go back and fish the hats out, even if they could find them, but by the next episode and for the rest of the season, they somehow have the same hats back again. (00:41:00)
Alias Smith and Jones (90 min.) - S1-E1
Continuity mistake: Deputy Harker keeps checking his pocket watch while making his rounds. The first two times he looks at it, the watch face has Roman numerals. On his third check, it has regular numbers instead. The fourth time, the Roman numerals are back again. (01:05:15 - 01:06:45)
Shootout at Diablo Station - S2-E11
Continuity mistake: In interior shots, the station's multi-paned window has dust and grime on all the panes. In exterior shots, as Curry talks to Lom from inside, it's apparent that there's no glass in the window at all. (00:41:00)
Factual error: Heyes and Curry spend months at the mine without any razors or knives. Their beards grow out - but their hair doesn't get any longer. (00:12:00)
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)
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)
Continuity mistake: At the campsite, Binford counts out 19 uncut diamonds that were "found" in the salted field. When that same stash is laid out on his desk later, there are 20 stones. And according to Heyes and Curry, there were 21. (00:33:50)
