Character mistake: At the Roadhouse Cooper states that the second victim (Maddy) was found dead two days ago. It has been less than 24 hours since the body was found: he likely means she was murdered two days ago.
Night of the Living Dummy III (1) - S2-E24
Character mistake: When Zane sees Rocky with the hockey mask, he seems legitimately terrified when he notices him. However, he was responsible for putting him there and no-one else was around. There is no reason for him to express real fear when he planned for his appearance the whole time. (00:11:44 - 00:12:08)
Suggested correction: He only pretended to be scared in order to fool his cousins, uncle and aunt.
Character mistake: Scully continually addresses the senior police officer as "Captain." But he wears sergeant's stripes. As a law enforcement officer continually dealing with other law enforcement officers, Scully is not likely to make this mistake. More likely a failure to match script with costume.
Character mistake: Tai says "And it started to snow in the middle of July" but later you find out that it takes place on August first.
Nobody Knows Anything - S1-E11
Character mistake: When Tony tells Dr. Melfi he feels as though a safe might fall on his head, she replies, "a feeling of pending doom." A woman of her intellect and education should know the proper word is "impending." "Pending" means something awaiting a conclusion. "Impending" means about to occur.
It Happened 'That Night' - S3-E1
Character mistake: Emily's mom tells Emily that reporters were there to talk to them about "Emily's missing remains." It's supposed to be "Allison's missing remains." (00:17:00)
The Way of the Warrior (2) - S4-E2
Character mistake: During the Defiant's flight to save the Cardassian officials, Worf says something to the effect of, "I've never been aboard a Federation ship equipped with a cloak before". However, he was aboard the Enterprise during the Pegasus incident, where The Ship was temporarily equipped with a cloaking device.
Hercule Poirot's Christmas - S6-E1
Character mistake: After Japp's arrival, when Poirot walks up the stairs with the two male detectives, at one point he says "Mais no madame." ("But no mylady.")
Character mistake: When the bodyguards enter elevators, they always enter last; they should be entering first to ensure it is secure. This is particularly visible in the hotel where the elevator can stop on any floor and Special Protection Branch does not have complete control of it as an express.
Character mistake: After the ship crashes in the city, Search and Rescue enter the scene to get people out of the buildings and ship and save lives. It's a rescue mission... so why the heck are they sending in soldiers fully armed with weapons drawn at the ready to rescue people from a crashed ship? The rescue team doesn't know of the alien threat inside. The people who sent them in also don't know. It was identified as a science vessel. Yet they go in armed with guns at the ready. (00:36:30)
Character mistake: When James Greer reviews Jack Ryan's military record, there is an entry that states he received the Marines Corps 'God' Conduct Medal. The word is meant to be Good. (00:31:09)
Episode #3.4 - S3-E4
Character mistake: DS Miles while in the chocolate shop tells Ana to go with "DCI Riley." Riley has the rank of DC, not DCI.
Character mistake: When Juliana puts the film on the projector she loads the reel backwards.The film is supposed to drop from the front of the reel, not the back.
Character mistake: Congressman Weitz tells the FBI task force that Kazahrus is an "absolute monarchy." Director Hirst interrupts him to state that this means "the order of succession is based solely on heredity," which she implies is well-known to students of civics. An absolute monarchy is one where the monarch's powers are unrestricted (such as by legislative or judicial branches of government). Hirst is describing a hereditary monarchy, but not all hereditary monarchies are absolute (for example, England's constitutional monarchy is hereditary), nor are all absolute monarchies hereditary (the Vatican's elective monarchy is absolute). What Hirst says is true of Kazahrus, but not of absolute monarchies, the term Weitz was defining. Weitz is presented as an expert on the topic, but doesn't correct her.
Character mistake: A shot shows Djimon Hounsou completing his year entry on a large chalk board. The entries are 20 years apart. The third entry on the second line is 2274, the next should be 2294, but instead it records 2394. The one after corrects the sequence with 2314. Considering there is an entry only every twenty years, you would think he'd be more careful. (00:20:15)
The Hammer - S1-E10
Character mistake: Raylan Givens tells Judge Reardon that he carries a ".45 Glock" but this is untrue. Throughout the series with the exception of the beginning of the first episode Raylan Givens carries a Glock 17, which is only chambered in 9mm parabellum. His backup can be seen to be a Glock 26 which is also in 9mm.
Duel Identity, Part II - S1-E30
Character mistake: Yugi mistakenly says if he doesn't get a monster out to defend himself Mai can attack him directly, which wouldn't be possible since the rules of Duel Monsters during the Duelist Kingdom arc forbade direct attacks on defenseless opponents. That rule wouldn't be implemented until the Battle City arc.
Character mistake: Patterson - the oceanographer - at one point claims that Lithuania is land-locked. She should know better; in fact, Lithuania has a coastline of close to 100 km on the Baltic Sea.
Character mistake: The 'perfect' German postcard Rollin has written is full of mistakes: 1) The 'sie' must have a capital 'S' because it's a personal pronoun; 2) The only sentence stops in the middle and makes no sense; 3) The word 'Besten' has to be written without a capital because it's not a noun; 4) In Germany the house number stands after the street name, not before; 5) The streetname makes no sense. Too many mistakes for a so-called 'perfect' card. (00:04:40)
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.
