Continuity mistake: One moment Frankie takes out two shot glasses and a bottle and starts to pour. She pours maybe one-fourth of one glass. The very next shot, both glasses are filled. (00:03:35)
Factual error: Chief Superintendent Hilton wears the ribbons of the General Service Medal (awarded for military service in a combat zone, most commonly in Northern Ireland) and the Police Long Service and Good Conduct Medal (awarded for twenty years' service), but not the Golden Jubilee Medal (awarded to all officers with five years' service in 2002), which he would also have. When he reappears in Series 4, he is wearing the Golden Jubilee Medal, Diamond Jubilee Medal (awarded in 2012) and Police Long Service and Good Conduct Medal, which would all be correct, but no longer has the General Service Medal.
Continuity mistake: Kurt is still recovering from the beating he took in the previous episode with bad cuts on his forehead, checks and temple area. They are red and impossible to miss while he is in the police station. The cuts have miraculously disappeared in the next scene when he goes to visit Mona.
Factual error: The show, which is set in California in 1947, mentions the gas chamber, lethal injection and the electric chair as methods of execution in the state. Two murderers are sentenced to death by lethal injection and one is depicted being instead executed in the electric chair, which the governor states has been brought out of retirement for the occasion. In fact, California adopted the gas chamber as its sole method of execution in 1937 (having previously used hanging). Lethal injection was not used in the United States at all until 1982 and not adopted in California until 1993 (becoming the prime method in 1996). California has never used the electric chair.
Here There Be Dragons - S2-E11
Visible crew/equipment: When Prax leads the group to where Dr. Strickland took Mei, just as they reach the door the two green and yellow T-marks are visible on the floor. (00:02:30)
What They Saw in Southie High - S1-E2
Other mistake: Agent Rohr asks who the cold case is related to. A dossier is given to him and the front cover contains a photograph and the name "Kanicki, K". Agent Rohr says "Kelly Kanicki" but there was no indication of the full name, just the initial. (00:08:30 - 00:09:00)
Other mistake: The shopkeeper hands Danny a Beretta 92fs/M9 handgun with a detached suppressor. To mount a suppressor to the muzzle end of the handgun the barrel needs to be threaded, and this one isn't. Sometimes barrels are threaded and when no suppressor is attached they are protected by a thread barrel cap to protect the threads from dings and bumps. There is no thread cap here either. (00:22:35)
Audio problem: The zombie chasing the man gets tangled on a wire fence and gets shot in the head. When the bullet impacts his skull he makes a grunting pain noise just like everybody else who gets shots in movies makes the same grunt. First of all zombies don't feel, so how can he express pain, and secondly when people get shot and die they don't grunt, they drop dead. (00:09:30 - 00:10:00)
Revealing mistake: Hannah sits in a conference room and pulls a landline phone towards her to dial her friend, asking about the will Owen left. The phone however isn't in any way connected, hence no call could have taken place.
Revealing mistake: When Captain Morrow welds the door to lock Zevari out of the Mother room, the computer screen reads "Crew Status?.. Crew Dead." In the next angle, this same text is reflected on Morrow's head, but it still reads the same way. The text should be flipped like a mirror since it's a reflection off his skin. (00:27:35)
Audio problem: They went to an investigator to let him listen to the audio. The audio with the woman screaming and the gasp, the gasp was Zak, not another apparition.
Continuity mistake: When Gary is at the end of the table talking about Golf, he's actually seated in front of the table as seen by how he grabs his cup in front of him. In the very next shot, he's no longer sitting in front of the table and is sitting past it.
Caleidoscope - S2-E4
Character mistake: The chess set in Dr. Pierce's home office is set up incorrectly. When the men are set up properly, each player has a light colored square in the right-hand corner. The board as it appears in the show is set up so that the light-colored square is in each player's left-hand corner. This "beginner" mistake puts the king and queen in the wrong positions.
Episode #2.1 - S2-E1
Factual error: Season 2 is set in 1979. Bill Tench and his wife are leaving the church and going to their car. Behind their car is parked a 1981 Chevrolet Celebrity.
The M.O.D.O.K. That Time Forgot! - S1-E2
Character mistake: M.O.D.O.K. refers to Hoobastank as "the Beatles of the late 90's." Hoobastank only released one album in the 90's, and they didn't become popular until after they released their second album in 2001.
The Family - S1-E6
Character mistake: The pharmacist says she's sorry, but they don't have the drug Lamotrigine in stock, so would the generic be okay?Lamotrigine is already the generic form of the drug Lamictal. (00:28:23)
Revealing mistake: In brother Justin's padded cell, the far wall is obviously a painted backdrop. It even flutters when the orderly and doctor walk in! The only solid part is a couple of feet at the end, that Justin leans up against.
Continuity mistake: As Dave is leaning over the edge of the air boat with Rose behind him, he pulls a chunk of metal out of the water and places it on the edge of the boat on his left side. When he gets up from his lying position moments later, the metal is gone. Moments later again, with an overhead shot of the boat, we see what appears to be that piece of metal positioned at what would have been his right side, not his left. This is also where we see him step over the seat (twice!) in subsequent camera angles. (00:30:00)
Factual error: At the beginning of the episode, Patrick Swayze is looking at photos of two Iraq veterans who have been murdered. He identifies one as a Marine Lance Corporal and the other as an Army PFC, but both pictures show men in U.S. Army uniforms. A bit later, his partner, who is supposed to be a Marine vet, refers to his decision not to "re-up," using the Army term for re-enlistment, rather than "ship over," as it's referred to in the Navy and Marines.
Containment - S1-E5
Continuity mistake: At the end of the episode, when the bad guy is preparing the syringe of small pox, he follows the usual method of tapping out any air in the tube - when he is shown injecting himself, a large air bubble is back in the syringe (which would probably kill him quicker than the smallpox).
