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.
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.
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.
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)
