Continuity mistake: When Helen pushes Seldon to his death, his body was facing to the right, but in next shot he is facing to the left.
A Nice Place to Visit - S1-E28
Revealing mistake: When Rocky evicts three women from the room and slams the door behind them, you can quite clearly see the entire wall shaking.
And When the Sky Was Opened - S1-E11
Revealing mistake: After his flashbacks in his hospital room, Forbes looks at himself in The Mirror and he cannot see his reflection. But you can still see his arm in mirror.
Continuity mistake: In the early scene when Bevis tumbles down the stairs of his apartment, a little boy watches and then holds his hands over his eyes. In the next shot, the boy is shown walking outside, but then the camera cuts and he is shown back inside, his hands still over his eyes.
Revealing mistake: In scene just after Rod Serling's opening narration, you can quite see that scene is being played in reverse because smoke is coming downwards back into the man's cigarette.
A Nice Place to Visit - S1-E28
Revealing mistake: After Valentine finds out he isn't in Heaven, he tries frantically to open the door. As he does, you can see the whole wall and door frame moving along with the door, showing that it's fake.
Continuity mistake: When Mr. Bevis starts his car, a girl with shoulder-length hair runs over with other children to help push it. In the first shot she's at the rear bumper but in the following shot she's beside the passenger door and there are different kids at the rear bumper. (00:03:25)
Continuity mistake: As Millicent starts toward the women's restroom, the door handle is to her right. However, in the next shot showing her in the restroom with the door now behind her, the handle is now to her left. (00:20:00)
Continuity mistake: When Martin meets his parents in their house, the door is split and closes in the middle with a screen. In the next shot, it is a full door without a screen.
Suggested correction: As seen from the exterior, the outer door is a very wide screen door with its handle to the left and hinges at the right. Behind the screen door are two solid doors which swing open inward from the center. Notice the wide screen door is the door Martin bangs on when his father closes the solid double doors (with individual doorknobs), and later in the episode when Martin's mother walks outside we see her push open the screen door.
Continuity mistake: After Decker escapes from being held and heads back to his plane, he does not have his overcoat or scarf, and does not put them on when he starts his plane and climbs on board. When Major Wilson lets him go and he's taxiing away, in one shot he has the overcoat and scarf on, with no time to do so.
Factual error: The Southern Pacific train that almost hits Nan's car did not serve the part of the US she was supposed to be in.
I Shot an Arrow into the Air - S1-E15
Other mistake: Corey sees a sign for Reno Nevada that is in the middle of nowhere, that can't be seen from the road in the distance. Who would see it?
Other mistake: Lt. Mueller's German accent drifts in and out.
Other mistake: When Ferris first arrives in the town the the church bell chimes seven times indicating it's 7 o'clock. Later the bells chime again but this time only four times indicating 4 o'clock. Surely he didn't walk around the empty town for 9 hours.
Suggested correction: Since the revelation of the episode is that Ferris is merely in a simulation, it stands to reason that they control how quickly time passes for him.
Plot hole: If Walter was indeed immortal from his deal with the devil then there was no reason for him to use the Escape Clause when he was sent to jail. Since he can't be killed by any means and nobody can harm him there would have been nothing to stop him from escaping the prison the moment his cell was opened.
Suggested correction: He may be immortal and not feel pain, but he isn't super-strong and can't walk through walls or people, so escaping wouldn't be trivial. That isn't to say it'd be impossible or even that hard, but this is a man who got centuries of perfect youth and health, and all he could think of to do were things that would kill a normal human (even though, again, he can't even feel pain.) He also confessed to murder to experience the electric chair, not considering that they wouldn't just let him walk away when he survived execution. He's a short-sighted, unimaginative moron, and that's probably why the devil chose him.
Suggested correction: Walter uses his Escape Clause because he doesn't want to live forever in a prison cell. Even if he could escape at some point, he's not willing to spend any time behind bars waiting.
Factual error: In his opening narration, Rod Serling says that he is quoting Shakespeare's play Richard the Third. His quotation is actually from Richard the Second, also written by William Shakespeare.
Revealing mistake: When the main character proclaims, ".the new Walter Bedeker!" you can see the frames are running back and forth. You can tell by looking at the window curtains behind him.
Factual error: Caswell acts surprised at the sight of the lighter, but lighters were around in his time.
Suggested correction: The modern lighter, which use ferrocerium to create a spark, was developed in 1903. Caswell was from 1880. This would have been different then anything he would have seen.
Other mistake: Bemis is happy because he has enough time to read all he wants, but all the food would be poisoned by the radiation and and even if it wasn't, meat and fish it would spoil from not being refrigerated.
Revealing mistake: One of the actresses who is supposed to be playing a mannequin doesn't start to smile until the camera is on her.
