The Lateness of the Hour - S2-E8
Visible crew/equipment: The boom shadow intrudes briefly at the upper left of the shot as Jana stands at the window and says, "Rest in peace." (00:16:15)
The Monsters are Due on Maple Street - S1-E22
Plot hole: The street sign in the beginning is all wrong: it faces the camera rather than the street where the story takes place. In a typical American city, street signs are almost always placed in the direction of the street they are indicating, so drivers on the other street in the intersection know what they are turning onto or passing. In other words, the story is not set on Maple Street! Maple Street is the intersecting street at the end of the road the story is set on.
Revealing mistake: At the end, though Williams is shot multiple times (by several rifles, no less), there's not a drop of blood on him and no holes in his clothes. Also, his "corpse" is visibly breathing. He's clearly meant to be dead, so the fact that he's an alien with healing powers does not explain why he's still breathing - or why the bullets left no holes or blood on his clothes. (00:22:30)
Continuity mistake: The laser burns on the back of the old woman's left hand disappear when the knife is slicing at her through the door. They return a few shots later, though. (00:10:30 - 00:17:30)
Nick of Time - S2-E7
Continuity mistake: After dodging the vehicles in the street, Don notices the time as 3 o'clock, when the machine predicted something would happen. When they go back into the diner, his watch has the time as 10:10.
Other mistake: If the crystal cracked on his pocket watch, why didn't his glasses crack, too?
Will the Real Martian Please Stand Up - S2-E28
Plot hole: At the end of the episode, the trooper answers the phone declaring the bridge is safe to cross but the driver is still worried. The trooper says "We'll go on ahead, cross the bridge first." When Mr. Ross returns to the diner, he tells Haley the bridge wasn't safe. It collapsed. The state police car, the bus, everything went into the river with no survivors, except him of course. Here's the problem. The troopers were going to cross the bridge first to check its safety, then let the bus cross (1 vehicle at a time). That means only one vehicle could have made the bridge collapse, not both at the same time. If the police car made it across safely, then the bus caused it to collapse. If the police car caused it to fall, the bus would not have gone anywhere near the bridge. Therefore, the story Ross gives Haley throws off the whole point of the police going across first.
Suggested correction: It's simply a story he made up walking back to the diner. It's clear he caused the bridge to collapse and made sure all the vehicles went in.
Doubtful. He was very clear and precise about everything that happened on that bridge. Besides, he explained exactly how he survived, and the plans of his friends landing soon. There were no more secrets at this point. Why make up the bridge story?
Originally, Ross tried to still convince Haley that he is a human and that he was lucky to be the only survivor. It wasn't until Haley confronted him with the fact that he was totally dry, despite just falling in the water, that he came out clean and admitted he is Martian. Therefore, the false bridge story could be part of his original attempt to conceal who he really is.
Suggested correction: Maybe they decided to change plan and go all together at last moment. Doesn't make sense, I give you that, but it could have happened. Plus, Ross could have used some Martian magic to make both vehicles go on to the bridge at same time. If he can make lights go on and off and jukebox go on and off and have a third hand, we can safely assume he can do more magic.
Mr. Dingle, the Strong - S2-E19
Revealing mistake: When Mr. Dingle lifts the bench, you can see the cables holding it up.
A Thing About Machines - S2-E4
Revealing mistake: When Finchley smashes the TV, the screen image stays visible for a short time after the screen is broken, revealing that the screen's image was superimposed.
Continuity mistake: When Decker first exits the aircraft, there is a jeep immediately behind it, a service truck behind the jeep, and a USAF F-100 Super Sabre jet in the background. However, when Maj Wilson escorts him away from the plane, the service truck is gone and the F-100 has been replaced with a large transport aircraft.
The Last Rites of Jeff Myrtlebank - S3-E23
Continuity mistake: Jeff corners Orgram behind a tree with a tire swing hanging from it and punches him to the ground. But in the next shot, Orgram is still on the ground and the tree and tire swing are nowhere in sight. (00:17:35)
Continuity mistake: After Nan sees Hitch-Hiker for first time and she starts speeding away, she has clear road both in front and behind her. But just seconds ago, a mechanic told her to follow him to his shop so he could change her tire. Where did he go?
Continuity mistake: When we first see it, the grandfather clock is stopped at 2:33. But when Alex opens the case to adjust and restart it, the clock reads 4:40, and he moves the hands to 2:33 after checking his watch. (00:01:05 - 00:03:50)
I Sing the Body Electric - S3-E35
Continuity mistake: When Tom races into the house, the exterior shot is of a front door with six window panels. But when we cut to the interior view of him coming inside, the door has suddenly become solid, with no windows at all. (00:13:20)
Continuity mistake: When the decrepit Mr. Holt gets his new young body (briefly necessitating a different actor in the role), his German accent mysteriously disappears. He gets it back when he returns to his old body. (00:21:00)
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.
Factual error: The Nazi symbol on the flag is reversed.
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: The clock in the booth with a broken face is shown in a distant shot, then in a close-up, where more cracks appear in it than before.
