Six Strangers at Apache Springs - S2-E7
Revealing mistake: During the saloon brawl, recycled footage causes Curry to change into his first season hat for a few shots. After the fight, he has his second season hat back on. (00:28:00)
The Posse That Wouldn't Quit - S2-E5
Revealing mistake: All the shots of the pursuing posse are "borrowed" footage, which might never have been obvious - except for the fact that one shot shows us a recognizable Heath and Nick Barkley from "The Big Valley" at the head of the pack. (00:17:00)
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.
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.
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)
