Mr. Dingle, the Strong - S2-E19
Factual error: Though this episode is set in then-present-day 1961, the fistful of prop money the bartender is holding is not contemporary. It appears to be copies of 1880s U.S. Currency, though it's been reproduced as smaller, 20th Century sized bills rather than the larger ones that were standard in the 1800s. All in all, not something his bar patrons would likely be paying the bartender with in the 1960s. (00:16:40)
Revealing mistake: In the boarding house hallway, Ed yanks the pay phone's receiver off the hook - and the entire wall to which the phone is attached wobbles. (00:11:00)
Continuity mistake: When the bottle falls on the shop floor, it changes positions between the time it settles and the moment it begins to smoke. (00:05:50)
Continuity mistake: The flying saucer the old woman hacks to pieces with an axe is noticeably not the same one that lands in her attic in the beginning. A cruder version was built for the axing scene because the model used was a studio keepsake - the original spaceship from the classic sf film "Forbidden Planet." (00:23:00)
Continuity mistake: When the man rolls the dice onto the bed, one falls off, yet in the next shot we see both of them land on the bed.
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)
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.
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.
Factual error: The Nazi symbol on the flag is reversed.
The Eye of the Beholder - S2-E6
Other mistake: For someone whose entire head has been bandaged for several weeks, Janet Tyler's curly hair is remarkably unflattened when the bandages are finally removed, and her thick mascara isn't smeared in the least. (00:00:15)
The Trouble with Templeton - S2-E9
Continuity mistake: At Freddie's speakeasy, when Laura lifts Barney's script from the table, she begins to fan herself. In the wide shot, the script's titled top page with corner diagonal stripes is gripped under Laura's four fingers, with the blank back page at her thumb. It cuts to a close-up, and now the script is gripped in Laura's hand the opposite way, with the top page at her thumb (the back page is blank).
The Trouble with Templeton - S2-E9
Visible crew/equipment: When Booth walks over to Laura and Barney at the speakeasy, the moving boom mic casts a shadow on the wood pillar behind Laura, at the top left side of the screen.
A Hundred Yards over the Rim - S2-E23
Factual error: Although set in 1847, Christian Horn is carrying a rifle made in 1884.
The Rip Van Winkle Caper - S2-E24
Revealing mistake: The suspension machines are nothing more than large terrariums, there doesn't seem to be any electronics or piping or machinery of any kind attached to them.
The Odyssey of Flight 33 - S2-E18
Character mistake: The real speed that was reported was 3,000 knots. At one point, the plane encountered a bright flash, and violent shaking. The Captain surmised that they broke the sound barrier. 3,000 knots equates to over 3,000mph. The sound barrier (Mach 1) is about 767mph, and the captain would know that.
A Thing About Machines - S2-E4
Revealing mistake: When the car is approaching the pool to push the man into the water, the tires tracks are visible in the grass, showing that the car had already made that trip. Either tracks from an earlier take, or the scene was filmed and then played in reverse, to be safe for the actor.
The Odyssey of Flight 33 - S2-E18
Continuity mistake: When the jet is preparing to land in 1939 New York City, the view of the crew from the back of the cabin forward shows the airliner captain wearing his headphones, but the next instant close up of him shows him not wearing the headphones.
