Other mistake: Old Ben duplicates Jenny so she can accompany him to his home planet. As he can turn into anything, he should be able to approximate her height. When the now twins walk out, the girl on the right is a couple of inches taller than the girl on the left. Not only that, but her hair is noticeably darker.
Showdown with Rance McGrew - S3-E20
Continuity mistake: Rance McGrew's white horse is tied up with its head just a few inches from the hitching rail, but a moment later is untied and several feet away from the rail. Next shot, it's tied up close again, though no one's touched it. Finally, it's completely loose, and at the episode's end, is wandering into the street. (00:22:00 - 00:23:30)
Showdown with Rance McGrew - S3-E20
Continuity mistake: The saloon's windows are much narrower inside than they are on the outside. (00:17:20)
Other mistake: Chambers asks what time it is on Earth, a strangely vague question to which the Kanamits grant an equally odd answer: on Earth, it is noon. It can't be noon everywhere on Earth at once. While it can be fancifully explained away ("They somehow knew to answer for the time zone he was taken from"), it still jars the viewer, because neither Chambers nor the aliens, both highly intelligent, should make this sort of imprecise mistake. Both director Richard Bare and Damon Knight, author of the original short story, confirmed this as a scriptwriting error that should have been caught before shooting began. (00:02:15)
Continuity mistake: The events shown are supposed to take place at almost exactly midnight, yet when Conny goes to the graveyard the sky is bright and everything is well lit, much brighter than moonlight. Just as he enters the graveyard there is an abrupt change in lighting and the scene is suddenly much darker.
Showdown with Rance McGrew - S3-E20
Continuity mistake: The car Rance drives onto the set can be seen in the street from inside the saloon, but disappears when Rance, in character, comes through the swinging doors. It's visible again in the very next shot, but vanishes anew when Jesse James comes through the doors, after which it yet again reappears in the very next shot. (00:04:30 - 00:07:20)
Continuity mistake: During the birthday party scene, as the close-ups and master shot are intercut, Anthony's hair changes back and forth from being combed straight forward to parted on the left and combed to the side. (00:15:10)
Revealing mistake: As Connie approaches the graveyard the sky in the background is obviously a painted backdrop, as there is a visible seam.
The Jungle - S3-E12
Continuity mistake: Richards opens the door and finds a lion on the bed over his wife's body. When the door first opens, the corpse has dark hair and the blanket is twisted and disarrayed. But when the shot cuts to the lion leaping, the corpse's hair is a lighter color and the blanket is neatly spread across the bed. (00:23:40)
Audio problem: The keys we see being depressed on the player piano never bear any resemblance to the actual notes we hear. (00:13:00)
Continuity mistake: When the Union soldier arrives on the horse, Lavinia points a shotgun at him, holding it at chest level. But when the shot cuts, she suddenly has it up to her cheek. (00:15:00)
Deliberate mistake: The signs at Dachau Concentration Camp are in English.
Factual error: Author Damon Knight was happy with Rod Serling's TV adaptation of his short story - except for the change that allowed the humans to translate the Kanamit language as though it were a code. Said Knight, "Without some sort of interplanetary Rosetta Stone, deciphering an unknown language would be impossible." (00:22:10)
Continuity mistake: The hundreds of ropes used by the tiny people to pull down Craig's statue vanish in the next shot, when the statue hits the ground. (00:23:55)
Showdown with Rance McGrew - S3-E20
Factual error: Throughout this episode, the TV western supposedly being filmed lacks several essential elements. There are no clapboards to mark the scenes; the modern-day car is constantly in shot through the swinging doors; and the set is located inside the "real" saloon when it should be on a sound stage.
Continuity mistake: When Fats makes his shot to set up the last ball for Jesse, the cue ball stops on the bumper side of the dot. When Jesse goes to take the shot, the cue ball is closer to the side pocket he's leaning over.
Hocus-Pocus and Frisby - S3-E30
Visible crew/equipment: After the two travellers have paid for their gas, when Frisby advises them to check in someplace because of the clouds, the reflection of the moving boom pole and mic can be seen above the word "shop" on the store window. (00:08:00)
Hocus-Pocus and Frisby - S3-E30
Visible crew/equipment: When Frisby tells the two travellers that they're looking at the grandad of the American automobile, we can see the reflection of a crewmember wearing a suit, possibly the director, who stands up from a directors chair (also seen in a following shot). Then as Frisby tries to locate the gas tank, the shadow of the moving boom mic is visible on the store's doors. (00:06:20)
Revealing mistake: In the window there are already broken areas where the glass gets broken when Captain hits it. On the bottom pane the grill on the top, bottom and right have a crack before the Captain even hits it. (00:19:00)
Continuity mistake: Block 6 looks to have a no cardboard over the window beside the "Block 6" sign. Then later on they have cardboard there. (00:12:20 - 00:14:55)
