Revealing mistake: When the Apache war party starts its charge toward the High Chaparral, the dirt road beside them shows clear tire tread marks from the camera truck. (00:30:05)
Continuity mistake: Sam walks out of the saloon without his gloves on, but emerges into the street wearing them in the very next shot.
Continuity mistake: Blue's arms at the jail cell window instantly switch back and forth from being together to apart to together.
Revealing mistake: The square base securing the knife sticking out of the abdomen of the army lieutenant is visible as he and Blue scuffle in the river.
Revealing mistake: The substitution of a "stunt horse" is noticeable here when Blue is thrown during an Apache attack. Before he falls off, his palomino horse has its usual blond mane and tail. But when the horse rears and he falls, it's another palomino with a grey mane and tail. The blond one is instantly back, though, when Blue gets up.
Continuity mistake: Manolito leaves the ranch on a black horse that changes, mid-ride, into his regular brown sorrel, "Macadoo." In later shots of the same ride, the black horse is back, but when Mano dismounts, he's with Macadoo once again.
Gold Is Where You Leave It - S1-E19
Revealing mistake: Buck lights the fuse and tosses the dynamite-filled barrel at the bad guys. We see the explosion. Unfortunately, after that, we can also see the intact barrel still rolling away in the dirt.
Gold Is Where You Leave It - S1-E19
Audio problem: After the Apaches rescue Blue, Buck signs to their leader and says, "Vaya con Dios to you too, brother." But his lips never move.
Gold Is Where You Leave It - S1-E19
Visible crew/equipment: Just before Buck tosses the barrel at the bad guys, a film crew member's shadow is visible on the adobe ruin's wall.
The Kinsman - S1-E20
Factual error: Dan's wanted poster features a high-resolution 20th Century photo. In the 1870s, particularly way out west in frontier Arizona, the technology to reproduce and print photos like this was non-existent. Wanted posters sometimes had sketches of outlaws, but most often, they contained nothing but the name, reward amount, the crime, and a written description. (00:15:30)
The Kinsman - S1-E20
Continuity mistake: When Manolito rides up to the house, Buck is grooming his horse, Rebel, while standing beside the animal's left flank. After a very brief cut to Mano and back, Buck is suddenly on Rebel's right flank, without enough time to have moved there. (00:34:30)
The Kinsman - S1-E20
Visible crew/equipment: In the final scene, light patterns from studio reflectors are moving on the sleeve of Blue's shirt. He's on horseback in the middle of the desert and is nowhere near water, shiny metal, or anything else that could cause such light reflections. (00:40:50)
Visible crew/equipment: When Buck and Manolito finally meet up with John, Blue, and the other men, Buck hands over Olive to Sam, and in the next shot of Mano and Blue the boom mic dips into view at the top of the screen. (00:43:45)
Visible crew/equipment: When Buck and Manolito are riding back with the little girl, right after Big John sees them, a white vehicle appears at the left of the screen. (00:54:00 - 00:55:00)
Continuity mistake: Mano's horse is shot and killed by the Apaches. But when we see a shot of the "dead" animal, it's not Mano's, but the horse Buck was riding (with a distinctive white blaze on its forehead). Apparently, Buck's horse was better at playing dead.
Continuity mistake: While Buck and Mano are chasing the Apaches, Mano's mount changes from a horse with a blond mane and tail to one with an all-brown mane and tail and back again.
Continuity mistake: As Victoria tends to him, the blood stains on El Tigre's bandages keep changing positions and patterns between shots.
Revealing mistake: At the end, El Tigre (Ricardo Montalban) is supposedly dead, draped over the horse as his brother leads them away. However, his right foot is in the stirrup, and it is obviously holding his weight...not dangling as the rest of the "corpse"
Factual error: In the final battle with the Apaches, Blue and most of the rest of the Chaparral men fire their 6-shooters dozens of times without ever reloading.
Revealing mistake: When Blue rides in with Moon Fire and Kelly, there are footprints visible in the dirt behind them. Several of the prints have distinctive patterned tread from what could only be 20th Century rubber-soled shoes.
