Continuity mistake: When Will tackles Andrew, his shirt is lifted up exposing a blue undershirt that's tucked in, which is also behind his gun. There's two shots of this, but in the next shot, right before Will punches Andrew, we don't see the undershirt.
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)
Other mistake: In this true crime show there are both reenactments and actual police photos used. The narrator states that thousands of rounds of ammunition were found in the home where a crime was committed. But the accompanying "Actual police evidence" photo that's supposed to be ammo is actually stacks of Kodak Slide Carousels. (My dad was a photographer and we had these in my house.) (00:29:15)
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)
Fresh-Like - S3-E4
Continuity mistake: Issa and Nathan both jump into a swimming pool and are shown going completely under water but in the closeups when shown talking their faces and hair are completely dry. (00:22:00)
Factual error: You can see the Unicredit Tower on the Milan skyline - the episode should be set in 1997 but the unicredit tower was built in 2012. (00:31:00)
Episode #1.1 - S1-E1
Continuity mistake: When Sidney is having his hair cut, the barber in the background starts to opens his newspaper. A shot later, from a different angle, he is reading still.
Continuity mistake: During the green race near the end, steel cars keep changing the amount of dirt and position of the dirt between shots.
Episode #1.1 - S1-E1
Continuity mistake: The characters are looking at the Ten Little Soldiers. When one of them (playing the role of Blore) is banging on the glass, you can see the hands of the mystery writer ("Lombard") leaning against the base. He's leaning on the top of the display case in the next shot. (00:22:10)
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)
Continuity mistake: The father of a teen girl murdered in CA receives a letter from a self-proclaimed psychic concerning the murder. He received it at his home in RI, but the letter is addressed to San Diego, CA. The address is shown twice. (00:08:00 - 00:14:00)
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.
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.
Factual error: The constables working at Scotland Yard are wearing the divisional letter 'S'. 'S' Division covered North West London, including Hampstead, Hendon and Golders Green. Its men wouldn't have been anywhere near Scotland Yard.
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.
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: The DI refers to the local policeman as "Officer" Fuller. No British police officer would use this term to refer to another British police officer. She'd have said Constable Fuller or PC Fuller.
Continuity mistake: Russell is beat up by his neighbor and his mouth, cheek and chin are smeared with blood. In the next closeup, Russell only has blood on his upper lip and cheek, not on his chin, and then the blood is back on his mouth, cheek and chin. (00:29:00 - 00:30:00)
