Factual error: Graham repeatedly sings a song he says his grandmother taught him: "Rufus Rastus Johnson Brown, What You Gonna Do When the Rent Come Round?" This was a Vaudeville stage composition written by Andrew B. Sterling and Harry Von Tilzer - in 1905. High Chaparral is set in the 1870s.
Continuity mistake: When Manolito wakes her up, Anita instantly changes positions on the bed between takes. She's lying on her side, but in the very next shot, she is suddenly on her back looking up at him. (00:20:00)
Our Lady of Guadalupe - S2-E13
Continuity mistake: When Father Sanchez contemplates tossing his burden over the cliff, the bundle he holds is neatly wrapped. When the shot cuts, however, the blanket wrapped around the statue is abruptly loose and disarrayed. (00:17:30)
Revealing mistake: Apparently, Buck getting thrown off his horse, whose name was Rebel, wasn't in the script. When it happens, a startled Cameron Mitchell shouts at the horse using its real name, Prince. Despite the blooper, the shot wasn't cut. In fact, it happens at least two more times in other episodes of the series. (00:08:00)
Continuity mistake: Inside the hotel, Manolito is wearing a white shirt. But when he walks outside, he has on his usual yellow-gold one. It turns white again a few shots later.
Continuity mistake: When he's escorting Victoria back to the ranch, Manolito's shirt collar is completely outside his jacket in all the full shots, but is tucked inside the jacket in close-ups. (00:24:00)
Plot hole: Manolito suffers a peculiar memory lapse in this episode. He's fluent in Apache, yet at first speaks to the children only in Spanish and urges Vaquero to translate. Later, though, he "recovers" well enough to speak to both Geronimo and the children in Apache.
Continuity mistake: Mano throws a lasso around part of the burning hay wagon and hauls it away from the building. The camera angle changes as the wagon is pulled out, and from one shot to the next, the flames completely disappear.
Continuity mistake: A dark brown moisture stain that forms a stripe down the back of Sam's coat disappears when he enters the church, reappears when he comes out, and vanishes again when he meets Trinidad in the graveyard.
Revealing mistake: When the rurales chase Manolito, he's riding Macadoo, his sorrel horse with the blond mane and tail. But the use of a stunt horse becomes obvious when Mano hides by leaping off into an arroyo and urging his mount to lie down beside him. Suddenly "Macadoo's" coat is a much darker brown and his mane and tail have also turned brown. He becomes a blond sorrel again, though, in the next scene.
Continuity mistake: Blue is struck by a rifle stock and has a bleeding wound on his left temple. A few shots later, though, the wound disappears completely. Several scenes later, it's back again.
Continuity mistake: In the opening sequence, when the stagecoach first overturns, only one wheel is left spinning. In the next shot, as the comancheros ride up to the wreckage, all four wheels are spinning.
Continuity mistake: The leather strap around Manolito's neck is sticking prominently up out of his shirt collar in all the over-the-shoulder shots, but it disappears every time the angle reverses to a frontal view. (00:36:00)
Continuity mistake: When Buck and Blue are playing their game on the tree stump, Buck's left hand is down at his side in one shot, then instantly tucked up under his chin in the next.
Continuity mistake: When the gunman shoots at Mano and Ebenezer from the upstairs window, Mano shoots back and hits him. We see the man fall back away from the window into the room. Yet in the next shot, he somehow reverses directions and falls forward instead, breaking through the glass and falling out onto the roof.
Revealing mistake: When Buck gallops away from Mano and the newly-rescued Sarah, two jet contrails are visible in the sky at the upper left of the screen.
The Last Hundred Miles - S2-E17
Continuity mistake: When John speaks to Cochise, two Apache warriors standing behind him change both their poses and their distance from John every time the camera angle reverses. (00:23:30)
The Stallion - S2-E1
Continuity mistake: While the black stallion prances in the corral, a bridle appears on his head, even though no one's gone near him.
Continuity mistake: At the end, Sarah leaps onto a horse, jumps the fence and rejoins the waiting Apaches. On the way, in between shots, her long green dress, which has been bunched up beneath her during the fence leap, neatly rearranges itself and drapes quite prettily over the horse on all sides, even though she hasn't had time to touch it.
For What We Are About to Receive - S2-E11
Continuity mistake: When Perlita opens her door to Manolito, there's a wooden bench just outside that wasn't there in the previous exterior shot of Mano approaching the door. When he leaves, it's gone again.
