Continuity mistake: When John confronts Joe about firing Jelks, Joe's hands change positions, from down at his sides to up at chest level adjusting his gloves, every time the camera angle changes. (00:22:50)
The Guns of Johnny Rondo - S3-E18
Visible crew/equipment: When Rondo and his son Dan ride through High Chaparral's gate, there are tire tread marks visible in the dirt.
Continuity mistake: While he's "dining" with Miguel and the banditos, Don Sebastian's position on the ground changes repeatedly as the camera angles shift. In most shots, he's reclining and leaning on one elbow. But in several others, he's sitting upright. (00:24:35)
Revealing mistake: When John runs out of the Simmons' house, a jet contrail is faintly visible in the sky at the far right of the screen.
Continuity mistake: A heavy black bag falls from the Simmons' wagon as they pull away from their house. A short time later, it has disappeared from the spot where it landed.
Revealing mistake: After Buck knocks Bates out, Victoria takes the outlaw's clothes as a disguise in order to escape. Miraculously, Bates' clothes, despite his being a foot taller and considerably heavier than Victoria, fit her perfectly. She doesn't even have to roll up the shirt sleeves or the trouser legs.
Revealing mistake: When Buck comes across the first of two bodies in the desert, we see only the dead man's booted legs protruding from the bushes. When he finds the second body, the exact same shot of legs and boots (with the same bushes and rocks) is used over again with the film reversed.
Factual error: The Apache spearhead Buck appropriates is very obviously made from machine-tooled steel. Indian tribes in 1870s Arizona made their weapons points from hand-knapped stone and on rare occasions, iron. They never developed steel-making technology.
Generation - S3-E25
Revealing mistake: Due to budget cuts in the 3rd season, an L.A. soundstage replica of the ranch house replaced the outdoor set, which was in Old Tuscon. The replacement was often painfully obvious. In this episode, a stock exterior shot of the real house, with its outside walls undecorated, contrasts with the mock-up, which has mounted cattle horns all over it.
Plot hole: Victoria asks her rescuers to take her to Rancho Velásquez. When they ask where it is, she says, "About 30 miles from here." Though she never indicates a direction, they reply, "Sorry, we're not going that way." (00:23:20)
An Anger Greater Than Mine - S4-E1
Factual error: Diego's straight razor has a bright blue plastic handle. (00:08:00)
Audio problem: When Buck orders the would-be killers out of the hotel room, his lips don't move in sync with the words he speaks.
Only the Bad Come to Sonora - S4-E3
Continuity mistake: The number of outlaws in the gang mysteriously increases during one chase scene. For most of the episode, there are only three of them. When they gallop off after Manolito, there are suddenly five. Next scene, there are three again. (00:20:35)
Only the Bad Come to Sonora - S4-E3
Continuity mistake: One of the bad guys rides the stolen black stallion throughout the episode - except when the gang rides away from the cantina. Then, all their horses are brown. Once they're out in the desert, the black horse reappears. (00:23:25)
Only the Bad Come to Sonora - S4-E3
Plot hole: Manolito trades clothes with the poor peon he meets on the road. But at the end of the episode, he has the same clothes that he gave away earlier (his usual outfit) back on again.
Revealing mistake: The doll standing in for Baby Joey is visible in one shot of Victoria carrying the child on horseback. The blanket slips, leaving the doll's stiff neck, plastic head and shock of sticking-straight-up nylon hair all in plain view. (00:10:15)
Plot hole: This episode comprises a flashback to the year 1866, but it sets up a chronology that completely contradicts the rest or the series. It contends that the Cannons moved west to Arizona in 1867. In the pilot and throughout the series, it was stated that they arrived in Arizona in the 1870s, at least ten years after the U.S. Civil War.
The New Lion of Sonora - S4-E14
Audio problem: During Don Sebastian's funeral, the single church bell is tolling. But the ringing sound effect continues after the bell itself has stopped moving. (00:07:55)
The New Lion of Sonora - S4-E14
Continuity mistake: When Buck tries to comfort a bereft Manolito, Mano is sobbing and leaning his forehead against a tree trunk. But when the shot reverses angles, he's abruptly standing upright a foot away from the tree. (00:14:10)
The New Lion of Sonora - S4-E14
Factual error: In the 1870s, poker chips were made of wood and either branded or painted with denominational values. But the brightly colored chips on General Casados' table in this episode are very obviously made of plastic. (00:38:30)
