Episode #1.3 - S1-E3
Continuity mistake: Vera fires the gun several times, and later tells Justice Wargrave that the gun is empty, meaning that all the cartridges in it would be spent. When the judge loads his one bullet into the chamber, he does so in a gun where all five cartridge svisible are unspent.
Factual error: In the mall where Jimmy meets Irene there is the Pandora logo in the background when Jimmy is going up the escalator. Pandora didn't open its first store in New Mexico until 2013. (00:27:00 - 00:28:00)
Todos Los Hombres del Presidente - S3-E9
Visible crew/equipment: During the car crash, one of the camera shots is from above and you can see a camera vehicle moving into the shot from the bottom with the camera mounted in front of the vehicle. (00:35:25)
Character mistake: The diploma on the wall in Connor's office for the University of Kentucky, "university" is misspelled "universisty".
Factual error: They used an EpiPen to bring Liv back but they're holding it backwards. The way it's being held, Ravi would have injected himself instead of Liv and she wouldn't be revived.
Revealing mistake: Towards the end of the episode she picks up her phone but the screen shows the incoming call still coming through, and the screen doesn't go dark when she puts it to her ear. (00:29:30)
Continuity mistake: When Angela's hookup leaves her on the balcony she has almost finished her cigarette, but when the camera switches back to her a few moments later (she turns around after the door has just been closed), she has an almost full cigarette once again. (00:02:25)
Plot hole: The car was tracked down by finding the original car key on Jimmy's body. If he had stolen the car from the original owner, how did he come to have the original car key?
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
Factual error: A 1973 Cadillac ambulance on the street is shown. The show is set in the 1960's.
Factual error: There is no way cops would just walk up and open fire on a suspect unannounced, not knowing if he is armed or not, and with an innocent bystander so close.
Episode #1.1 - S1-E1
Continuity mistake: When he is asked "The culprit is a woman, isn't it?", the doctor is suddenly holding the pen between both hands instead of just with the right hand. (00:29:55)
Factual error: The detective constable is addressed as "Sir" by uniformed constables. They actually hold the same rank. Detectives do not outrank uniformed officers in Britain.
Running with the Devil - S1-E2
Factual error: The show is set in 1982. However the dedicated song on the radio is Mötley Crüe's "Shout at the Devil", which wasn't released until September 1983.
Character mistake: In an early episode, Villa mentions Rosewood's "banana colored" '69 GTO to his then girlfriend. Rosewood's GTO is a "banana colored" '68 GTO.
Factual error: Many elements of Marlott's trial and execution are incorrect. The judge sits with two assessors (a European practice, not a British one). He is addressed as 'Your Honour' instead of the correct 'My Lord'. He instructs the jury to find Marlott guilty and then goes straight to sentencing, which would never happen; a judge can instruct a jury to acquit, but not convict. He puts the black cap on himself, instead of an attendant doing it. The form of words for the death sentence is incorrect. The chaplain (who appears to be Catholic, not Anglican) gives a speech at the scaffold.
Revolution 1 - S2-E4
Factual error: Hodiak is having breakfast at a dinner. There is a sign for breakfast with a price of $4.95. In 1967 the price for breakfast would have been around $1.25 or less. Minimum wage was $1.60 an hour and the price of a big Mac, for example, was $0.50 and fries $0.10. So a $4.95 price for breakfast is just ridiculous.
