Palimpsest - S1-E6
Other mistake: During the credits, it lists Gloria Mundy as the actress who played Alison Araya. However, Araya is the actress's real name and Mundy is the character's name.
The King of the Delta Blues - S2-E6
Character mistake: "Are you going to send in the calvary?" is said twice. It should be "cavalry". (00:09:40)
Continuity mistake: When Dmitri and the doctor first try to get Vanessa to feed on human blood, the blood bag keeps switching from full to half-empty from one shot to the next. (00:16:05)
Other mistake: Issac is on the phone with his boss and he is holding his phone upside down, noticeable because his otter box case is upside down. (00:14:41)
Factual error: A 3 series BMW from either 1979, 1980, or 1981 shows up in 1973 New York city. (00:32:15)
Continuity mistake: In the original show we are led to believe that Lorelei lost her virginity to Christopher. But in this, during the late night gathering outside after the funeral, Lorelei's story about her father was about her losing her virginity to someone who wasn't Christopher. She got pregnant at the age of 16. We are to assume that she did not sleep with anyone immediately after Christopher. If the above is true, she didn't get pregnant when she lost her virginity. If she didn't get pregnant then she should've been safe with Christopher. What did the above were true, we would have heard about it. She would have told her daughter about how she lost her virginity.
Continuity mistake: Harry drives away from a crime scene and his rear numberplate is visible as D703 VAN. We then see Harry in his car from the front, and the numberplate has changed to E160 HLT. (00:21:18 - 00:22:31)
Revealing mistake: Right after the scene in Wallace's office where the DHS tries to shut down Hayes' investigation, the scene shifts to a montage. Towards the end of it there's a loop: in the bottom left corner you can see someone on a scooter appear from the left, only to disappear a second later and reappear from where they'd come the first time. (00:20:00)
Factual error: Pierre Bezukhov's spectacles are of the type with nose pads, which were not invented until the late 1920's.
Factual error: The judge requires £100,000 to be paid to the court in bail and Yvonne's husband later says he had to cash in bonds to get the money. In Britain, bail is not paid in advance. It is sufficient to prove that it is available if necessary and it is only required to be paid if the defendant later absconds.
Episode #1.3 - S1-E3
Factual error: Dunn says he's researched at the British Library. It wasn't called that until 1973. Before then it was the British Museum Library and always referred to either as that or simply as the British Museum.
Sublimation - S2-E3
Continuity mistake: When Katie is talking to Grace, she has the works of Confucius under the Bible and Koran. When Grace says she likes how people won't die any more, the shot changes and the works of Confucius is now on top.
Factual error: Wilshire Grand Center is visible in the skyline, but it was constructed starting in 2014, 10 years after the murder. (00:51:09)
Episode #1.2 - S1-E2
Factual error: The railway tickets just say "Kent to Greenwich" instead of specifying the actual station where they were bought as they would have done.
Revealing mistake: As Sgt. Cain and Chief Lain stand by Marjorie's dead body lying on the hotel bed, discussing her death from an overdose, you can see her stomach rise and fall slightly, though she's supposed to be dead. (00:18:00 - 00:20:00)
Factual error: Cars in Thailand drive on the left side of the road with the steering wheel on the right, unlike the ones shown in the episode.
Factual error: The Metropolitan Police isn't a national police force (except for close protection and anti-terrorist matters). It has no authority over other police forces. It doesn't take over criminal cases from other police forces. It hasn't even provided investigation teams on request for decades. Every force handles its own investigations. A Met chief superintendent and his team coming in, as depicted here, and taking over an Avon and Somerset investigation just wouldn't happen.
Visible crew/equipment: While Michael sits outside of a hospital room in the hallway, there is a clear reflection of equipment in front of him. (00:21:00)
Factual error: Almost all the people being shown skydiving have no experience doing it, but the instructor allows them to jump out of the plane unassisted after only giving a theoretic introduction into the subject. First time skydivers are always assisted in some fashion, usually through a tandem-jump or a parachute opened by a line attached to the plane.
Factual error: At the picnic, a woman says she is going to New York by train. It is 1828. Railway passenger service in the United States did not begin until 1830 and it would not be possible to travel from North Carolina to New York until some years after that.
