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.
Continuity mistake: While Curry and Heyes are panning for gold, the same shot of someone's bare arm and shoulder above the gold pan is inserted several times. But neither Heyes nor Curry is shirtless, and no one else is with them. (00:11:05)
The Reformation of Harry Briscoe - S2-E9
Continuity mistake: Molly's hands are tied with leather straps. But when Briscoe and Sam barge into the campsite, she pulls off her blanket and stands up with her hands free. A moment later, she once again has the leather straps binding her wrists. (00:30:15)
Dreadful Sorry, Clementine - S2-E10
Factual error: Heyes burns the photo - but he shouldn't have been able to. In the 1880s, it should be printed on tin and not on paper. (00:11:00)
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.
Shootout at Diablo Station - S2-E11
Continuity mistake: The stage driver's hat is white when they leave town, black during the trip, and white again when they arrive at the station. (00:02:00 - 00:05:15)
Shootout at Diablo Station - S2-E11
Continuity mistake: Four horses pull the stagecoach. In long shots, the left lead horse has white fetlocks. A moment later, when the coach pulls into the station, the white-legged horse has moved to the leading right position. (00:05:00)
Shootout at Diablo Station - S2-E11
Plot hole: Well within earshot of the others in the small room, Curry comments to Heyes (purely for the viewers' benefit, since Heyes already knows it) that if Lom Trevors is killed, their amnesty will go with him. This information should have blown their cover, but for some strange (and unbelievable) reason, no one wonders what he's talking about. (00:19:00)
Shootout at Diablo Station - S2-E11
Continuity mistake: The stagecoach station during the day and what is supposedly the same station after night are shots of two completely different buildings. The night shot is stock footage of a different set. (00:19:10 - 00:35:00)
Shootout at Diablo Station - S2-E11
Continuity mistake: Gorman's left hand is in two places at once during the card game. We see it resting on his thigh under the table. One shot later, without time for him to move, both his hands are holding his cards. (00:19:30)
Shootout at Diablo Station - S2-E11
Plot hole: Curry slips out of his bonds and hides in the secret cubby hole beside the fireplace, right under the four dozing outlaws' noses. But when he's found, the wooden door over the hiding place has to be pried off - very noisily. No one else was free to nail that door shut, and there's no way he could have done it from inside - at least, not without waking up the outlaws. (00:30:30 - 00:34:50)
Shootout at Diablo Station - S2-E11
Continuity mistake: In the interior shot, Hayfoot walks out the door with the flag under his right arm. He then immediately emerges in the exterior shot with the flag under his left arm. (00:37:30)
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)
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: During the second funeral, Heyes' hair is wind-blown and disarrayed in close-ups, but neatly combed in all the full shots. (00:23:30)
Revealing mistake: The night scenes around the campfire are plainly shot on an indoor set and not outdoors. Phony exteriors were seldom used on this series, but L.A. had suffered a record five inches of rain that forced the crew to either shoot indoors or fall behind schedule.
The Man Who Broke the Bank at Red Gap - S2-E17
Continuity mistake: Heyes and Curry are waiting at the granary at 10 p.m. at night when they hear the posse approaching. In the next two shots of the riders coming over the hill, they're under a blue sky in full daylight. (00:15:05)
The Man Who Broke the Bank at Red Gap - S2-E17
Factual error: An egotistical, prissy and dishonest lawyer like Mr. Fletcher wouldn't make the mistake of allowing his name to be misspelled on his office door. It reads "Winfred Fletcher." His first name, as it's pronounced throughout the episode, is "Winford." (00:26:50)
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)
The Men That Corrupted Hadleyburg - S2-E18
Factual error: Heyes plays blackjack with cash instead of chips. When he bets the limit of $1000, he pushes two small stacks of coins toward the dealer. A thousand dollars in coins would have made a substantially larger stack than this. Even if they were $20 gold pieces (which they don't appear to be) the two piles would have to be comprised of 25 coins each, which they are not. (00:30:00)
