Other mistake: When Lillian calls Oliver, she tells him that the car stalled at 3rd and Park - the original scene of the accident. Later, when Oliver goes into his garage in the middle of the night, the car turns on its radio and goes to a news broadcast about the hit-and-run that took place at 3rd and Elm.
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.
On Thursday We Leave For Home - S4-E16
Visible crew/equipment: As the men talk in the cave, the boom mike is plainly visible.
Of Late I Think of Cliffordville - S4-E14
Other mistake: When Feathersmith meets Devlin it's 1963, and he's 75 years old, which means he would have been born in 1888, so in 1910 he would have been 22, not 30. Otherwise, he'd be an 83-year-old man.
The Rip Van Winkle Caper - S2-E24
Factual error: When they looked at Mr. Herbie's case, they only saw the skeleton. Problem is the clothing was missing, where there should have been some remnants. And the vehicle started with no trouble. After a hundred years, the battery should have been dead, and the engine inoperable.
Revealing mistake: The strings on the guitar are extremely loose. While they would make a sound, it wouldn't be anywhere near the proper sound. The guitar sound throughout the episode doesn't match up to the strokes of the guitar either.
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.
A Hundred Yards over the Rim - S2-E23
Continuity mistake: When Joe (the diner owner) hands Christian Horn the glass of water, Horn grabs it by the base of the glass and drinks from it holding it the same way, almost to the last drop. The camera quickly switches the angle to show Horn finishing it close up, but this time he's holding it with his fingers wrapped around the glass. The camera switches the angle again as he's handing it back to Joe, once again holding it by the base.
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: The woman leads a simple but hard life, however, in several close ups, she has long, tapered, finely manicured and polished fingernails.
Factual error: When McNulty clicks his stopwatch the helicopter is shown frozen in flight but the blades are shown as a blur, they should be just as much in focus as the rest of the helicopter.
Will the Real Martian Please Stand Up - S2-E28
Continuity mistake: During the scene in the diner between Ross the Martian and Haley the Venusian, there are objects such as a napkin dispenser visible on the counter over the left arm of Haley, which then disappear in the shots over Ross' right arm.
Factual error: The baseball field is said to be in Hoboken, New Jersey, but palm trees are visible outside the ballpark at the beginning of the episode.
Factual error: As well as the obvious problem with translating an unknown language as if it was a code, there is no chance that the word "serve" would have the same double meaning in English and Kanamit. It would be like the word "dope" and its French equivalent meaning "idiot" and "illegal drugs" in both languages.
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.
Factual error: The Nazi symbol on the flag is reversed.
