Revealing: 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.

Continuity: Sam walks out of the saloon without his gloves on, but emerges into the street wearing them in the very next shot.

Revealing: 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: 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.

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.

Continuity: 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.

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.

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.

Continuity: 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.

Revealing: The dead soldier is still holding the coin with which Manolito paid him for the horse. But when the camera pulls in close, it becomes apparent that the "coin" is actually a blank disc.

Continuity: 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: As Victoria tends to him, the blood stains on El Tigre's bandages keep changing positions and patterns between shots.

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: 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.

Revealing: Henry Darrow's stunt double is very noticeable during the final fight scene with Ramon. He's heavier, taller - and is wearing a very bad wig.

Factual error: Ramon's six-gun fires more than a dozen times without ever being reloaded.

Continuity: Manolito is bitten on the right ankle by a rattlesnake. But when Maria is later adjusting his bandage, she doctors his left leg instead.
