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.
Continuity mistake: Manolito is bitten on the right ankle by a rattlesnake. But when Maria is later adjusting his bandage, she doctors his left leg instead. (00:01:10 - 00:09:15)
Factual error: Ramon's six-gun fires more than a dozen times without ever being reloaded. (00:37:00)
Revealing mistake: 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. (00:44:30)
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.
The Stallion - S2-E1
Continuity mistake: Blue leaves his regular horse exhausted at the ranch and takes another one in order to pursue the young Apache. But in mid-chase, Blue is suddenly back on his regular horse again.
Continuity mistake: In the opening scenes, the perspiration stains on Blue's shirt disappear between takes. They return a few moments later, only to vanish and reappear several more times in subsequent shots. (00:05:00)
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: Two of the ten orphaned Apache children are found hiding near the house, bringing the total so far to six. But later, after Chodi sends out a signal, two more children come in from the desert, and these are again counted as five and six. But the fifth and sixth of the children were already there - so the new total should have been eight, not six.
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.
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.
Revealing mistake: At the end, we see insert close-ups of several of the pueblo's residents. But they're exactly the same shots we saw near the beginning of the episode: the same people in the exact same positions, shown in the same sequence. The footage is recycled.
Revealing mistake: During the fiesta, Reno plays his guitar in the canteen. Each time the musical chords change, we should see his left hand shift positions on the neck of the guitar. But though his right hand is vigorously strumming the strings through several chord changes, his left hand never moves.
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.
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: 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.
Audio problem: John and Manolito are driving the wagon and loudly singing "La Gallina" together. But as they pass closer to the camera, we can see that their lips aren't moving.
Continuity mistake: Victoria is wearing a torn white blouse after the stage coach overturns, then, after she and Jim are walking through the desert, and they find water, she is wearing a pristine pink blouse. Then, a later shot shows the white blouse again, and while she and Jim are camping for the night, she is shown changing into the pink blouse.
