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)
Something to Get Hung About - S2-E6
Revealing mistake: When Heyes rides away from the hotel in the beginning, he's passed on the street by a tall man in a white shirt riding a black horse and slouching in the saddle. When the shot cuts back to the front of the hotel, the same extra on the same horse rides by again, going in the opposite direction. (00:02:20)
Something to Get Hung About - S2-E6
Continuity mistake: After getting filthy in a street fight, Curry goes into the hotel and is immediately clean again.
How to Rob a Bank in One Hard Lesson - S2-E2
Continuity mistake: In the sheriff's office at the end, Heyes and Curry instantly switch positions between takes. (00:45:40)
The Day They Hanged Kid Curry (90 min.) - S2-E1
Factual error: Wheat refers to the hanging of real-life outlaw Black Jack Ketchum. But Ketchum was executed in 1901. Smith & Jones is set in the 1880s. (00:27:50)
Don't Get Mad, Get Even - S2-E21
Factual error: A grumpy Heyes tells Georgette and Curry that he's been sleeping in a stable loft for two days without a bath or a shave. But he's completely clean-shaven: not even a hint of stubble showing. (00:15:00)
Suggested correction: He is not "completely clean-shaven." He has evident facial hair.
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)
Which Way to the OK Corral? - S2-E20
Other mistake: When Neville Brand is listed as a guest star, guest star is misspelled as "Guast Star." (00:05:08)
The Men That Corrupted Hadleyburg - S2-E18
Factual error: Heyes and Curry are reading the Denver Post in the beginning scene, but the Denver Post was not published under that name until 1901, nor published under its earlier name, The Evening Post, until 1893.
