Other mistake: Several people, believing a treasure is hidden inside the Trails End saloon, are tearing the wooden building apart. To stop them, Joe pulls out his gun and fires a shot into the ceiling. Even though he held the gun at a 75-degree angle in front of him, the falling dust and plaster land directly on top of his head.
Other mistake: The episode opens with Ben Cartwright ascending an outdoor staircase to a land office. The sound of a howling wind can be heard but no dust or leaves are blowing and all the surrounding bushes and trees are motionless.
Blind Hunch - S13-E9
Continuity mistake: Jamie and a blind man are riding side by side on horseback along a trail. Upon hearing the sound of a bird, the blind man identifies it as a black-tailed magpie. Jamie looks up to see the bird. The next shot, obviously from stock footage, shows a bird sitting on a branch of a tree with no leaves. In the scenes with Jamie and the blind man, every tree is fully grown with leaves and there are no bare branches.
Continuity mistake: April Christopher is asleep in an upstairs bedroom at the Ponderosa. After a noise awakens her, she gets out of bed, puts on a robe and leaves the room. As she is going downstairs, she is suddenly also wearing a pair of blue slippers.
Continuity mistake: During the final minute of this episode, the sound of a roaring wind can be heard. Two close-ups of a statue and a close-up of a boy in the street show swirling dust and leaves. In the long shots, there is no evidence of wind. No dust is blowing and all the trees are completely still.
Factual error: The wife of a former Civil War general who is being encouraged to run for Governor tells Ben Cartwright, "He's used to being in The Spotlight." This series is set in the 1880s and the word "spotlight" did not enter the English language until 1904.
The Lady and the Mark - S11-E18
Continuity mistake: A young woman named Charity is fishing from the shore of a lake. The water is a deep blue color and there are no rocks. When she gets a bite, the close-up shows a fish flopping amid several rocks in shallow blue-green water.
Continuity mistake: Ben Cartwright and a man named Gunny are driving a team of six horses and a wagon in a race with two other men with a six-horse team and wagon. The winner will get a contract to transport mail. During a part of the race which goes through a dense forest of 40-foot-tall pine trees, a close-up of Ben and Gunny shows only blue sky and no trees.
Visible crew/equipment: Sam enters the livery stable to confront two men who attacked his son. The next scene, filmed from inside the stable, shows Hoss opening the livery stable door and entering. Two crew members, one wearing a blue T-shirt and white shorts, are visible in the distance. They are standing by what appears to be the framework of a building under construction.
Revealing mistake: The courthouse sits above a mine shaft. Blasting in the mine causes a portion of the courthouse to collapse. Fallen bricks, lumber and other debris trap Ben and four others in the vault room beneath the main floor. The shaking of the vault room was obviously simulated by the cameraman shaking the camera back and forth. The table, chair, books, file box and other objects in the room do not move.
Mrs. Wharton and the Lesser Breeds - S10-E17
Other mistake: Candy is fighting with two of Billy Buckner's men outside their mountain cabin. It is obvious that artificial lighting was used because each man casts two shadows.
Other mistake: Calvin Dorcas enters the Ponderosa home and slumps into a chair. Ben asks, "What happened to you?" Calvin explains that he fell into the river while searching for his granddaughter. However, his clothes and his hair are completely dry.
Continuity mistake: The schoolhouse has two windows, one on either side of the door. From inside, the view out the windows is of a grove of pine trees. This is obviously a painted backdrop. When the students exit the schoolroom, the nearest tree is a large white-limbed tree with no leaves.
Revealing mistake: The scene outside the window of the dining room is obviously a painting and it does not match the scenery shown in exterior shots of the home.
Revealing mistake: Joe and Eddie are in a corral in a big valley, taking turns trying to tame a horse known as Hammerhead. In the long shots, obviously using stunt doubles atop the horse, Hammerhead is bucking and running. The close-ups of Joe and Eddie show them only from the waist up and they are not moving forward. They are simply bouncing up and down. In addition, the close-ups show only blue sky and not the surrounding hills.
Other mistake: A crowd of men is awaiting the arrival of saloon singer Dolly Bantree. When the stage pulls up, she exits carrying a small bag. Hoss offers to carry her luggage and then is dismayed when the stage pulls away and he sees 20 more bags stacked in the street. The 20 bags were not atop the stage, nor would there have been room for them inside the stage.
Visible crew/equipment: Ben and Hoss, on horseback, are driving a herd of horses down a trail that leads back to the Ponderosa. In a close-up of the two men, the tire tracks of the camera vehicle which is in front of them can be seen on the trail behind them.
The Trouble with Jamie - S7-E25
Continuity mistake: Little Joe is pitching hay into the cattle pen. A load of hay lands on the head of a calf. In the long shot, the calf has no hay on its head. In the next close-up of Joe and the calf, the hay is back. It disappears again in the following long shot.
Continuity mistake: Near the start, the sarge orders the men to prepare to mount up, the soldiers walk over to the horses, and are ordered to mount. The soldier right behind the main characters starts to mount but has trouble and falls back down. Then they go to a wide angle shot and everyone is mounted.
Audio problem: During the trial of gunslinger Duke Miller for murder you can hear repeated sounds of the gavel being hammered down by the judge. On several of these occasions you hear the gavel but the judge never moves, nor does he have the gavel in his hand.
