Living Doll - S5-E6
Continuity mistake: After Erich takes Talky Tina back out of the trash can and pulls her from the burlap bag, the doll's left arm is pointing straight up above its head. When the shot cuts to a different angle, the arm is suddenly down at Tina's side, even though Erich didn't move it. (00:20:30)
Continuity mistake: Just before Sport and Jeb come back from their first visit with Aunt T, their parents are walking around the pool deck where it's fairly dry. But when the children come back, the area where they are helped out of the pool is suddenly very wet, probably from earlier takes. (00:13:40)
Deliberate mistake: The first of two twists meant to come at the end of this episode was the revelation that the mysterious dark rider chasing Anne was herself - 25 years in the future. According to writer Richard Matheson, the director chose, for some bizarre reason, to deliberately spoil this "reveal" by inserting a close-up of the rider early on, showing the viewers who she was at the outset.
Nightmare at 20,000 Feet - S5-E3
Revealing mistake: At one point, when the gremlin is about to rip open part of the engine, you can see he has a white sole on his foot, part of the costume.
Continuity mistake: When Sport and Jab jump into the pool for last time, Sport is seen wearing a shirt. But,when she comes out at Aunt T's house she is wearing a swimsuit.
Mr. Garrity and the Graves - S5-E32
Revealing mistake: When the town's people are waiting for Garrity's arrival at midnight, we hear an old clock informing everybody it is midnight and they all turn around to see. But look at the time on the clock - you can quite clearly see that it is actually five minutes till 6 o'clock.
Continuity mistake: At the beginning, The main character is driving a car and hits a bicyclist and kills him. The inside shots from the car show the driver's window closed. The outside shots show the driver's window open.
Continuity mistake: After McNulty freezes the office, a co-worker is getting water from a faucet, and the water is frozen in motion, but right before McNulty unfreezes the office, a female co-worker is in the background at the faucet with no water coming out of the faucet.
Other mistake: When Martin Landau throws the mini tape player to the floor, you hear the fast forward chipmunk sound but the reels are still spinning at the same speed as before.
The Brain Center at Whipple's - S5-E33
Continuity mistake: At the moment Chief Engineer Hanley turns off the projector, the lamps in the background come on at precisely the same moment. Mr. Whipple is standing in the middle of the room. No one else was in the room to turn the lights on.
Continuity mistake: When Joe goes to punch the TV screen, it shows moving lines and static. But in the shot where his fist goes through the screen, it's easy to see that the screen has been replaced with one on which wavy lines have simply been painted, and then backlit. The lines are still visible on the shards of glass after the screen is broken.
Living Doll - S5-E6
Visible crew/equipment: When Talky Tina calls Erich, the camera zooms in as Erich starts talking - and its shadow appears on his arm.
Other mistake: As Trooper Franklin is shining his light on the side of the car showing the fingerprints, notice the front passenger's door. The key hole and the black painted rim of it is not covered by the fingerprint, or paint as it turns out to be. But regardless, it's not covered. (00:14:15)
Stopover in a Quiet Town - S5-E30
Revealing mistake: The actors are supposed to be in a play set for the huge child, but when she reaches down and picks them up it is obvious that it was filmed in an outdoor setting in a town much bigger than what is supposed to be the play set.
From Agnes - With Love - S5-E20
Character mistake: Using a Texas Instruments TI-89 Titanium, the seventeenth root of 9,000,355,126,606 is 5.781163783, which means the first prime number greater is seven.
