Jailbreak at Junction City - S2-E3
Revealing mistake: The outlaws all have their hands tied behind their backs. But the one wearing glasses, apparently unaware that he's in the shot, brings both hands up to push the slipping glasses back up on his nose, then quickly puts his hands behind his back again.
Don't Get Mad, Get Even - S2-E21
Plot hole: In the bath house at the beginning, Heyes and Curry, who should be using their aliases, call each other by their real names several times while the proprietor, who's a stranger to them, is preparing hot water nearby. The man must not be up on "the two most successful outlaws in the history of the west," though: he doesn't race off to turn them in and collect the reward. (00:04:40)
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 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.
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.
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: 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)
Which Way to the OK Corral? - S2-E20
Factual error: Heyes and Curry meet Doc Holliday and Marshall Wyatt Earp in Tombstone. Wyatt, however, was never a marshall in Tombstone, though his brother Virgil was. Wyatt and Doc Holliday both left Tombstone permanently shortly after the OK Corral shootout in 1881, so wouldn't even have been there when Heyes and Curry arrived in 1883. (The year's established by Heyes reading Twain's book published in that year).
How to Rob a Bank in One Hard Lesson - S2-E2
Continuity mistake: When Harry tosses the cloth bag toward the well, it lands on bare ground with a few strands of straw nearby. But in long shot, it's surrounded by heaps of straw. (00:43:30)
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)
Bad Night in Big Butte - S2-E23
Continuity mistake: It's a major plot point that Big Butte's hotel has had a third floor added since the stolen diamond was hidden somewhere in its walls. But in exterior shots, the hotel has only two floors.
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)
The Day They Hanged Kid Curry (90 min.) - S2-E1
Continuity mistake: In full shot, Curry is leaning against the courtroom wall to the right of the door. When the shot cuts to a close-up, though, he's on the left side of the door. (00:06:00)
The Posse That Wouldn't Quit - S2-E5
Continuity mistake: When Heyes and Curry stop Belle's wagon, Heyes is holding his hat in his right hand. When the shot changes angles, the hat jumps instantly into his left hand. (00:05:40)
How to Rob a Bank in One Hard Lesson - S2-E2
Plot hole: Heyes convinces the deputy that they're not Heyes and Curry and rightfully pins the bank robbery on Harry, who forced him to break into the safe. But it had been previously stressed that only Heyes could have cracked that particular safe, something the governor knew. So the neatly tied-up ending doesn't really work. The governor would still know that Heyes (whose nitroglycerin method was based on a real bank robbery of the era) opened the safe.
How to Rob a Bank in One Hard Lesson - S2-E2
Continuity mistake: Harry sets the can of red putty down on the desk in front of Heyes. When he first places it, the label is facing the camera. When the shot cuts to a wider angle, the label has rotated itself 90 degrees and is now facing Heyes. (00:19:40)
Which Way to the OK Corral? - S2-E20
Continuity mistake: When Georgette tells him she plans to become a chanteuse, Curry says he doesn't know what that is. But in an earlier episode, "Journey from San Juan," he called Michelle a chanteuse with obvious knowledge of the word's meaning.
Which Way to the OK Corral? - S2-E20
Continuity mistake: At the end, Heyes and Curry tie their horses to the back of the stagecoach and get aboard. In the following shot of the coach pulling away, the tied horses are no longer there. (00:48:00)
