Protect Her - S1-E1
Factual error: When Jules and Hannah are talking about the financial shenanigans at Owen's firm, Jules says that the owner of Owen's company had fraudulently driven up the price of the stock before the IPO. This is impossible. The IPO is the first time the shares become tradeable.
Factual error: Constantine's driving licence is shown - it's a UK licence, but no. 7 where his signature should be is blank, and no. 8 where his full address should be simply says "England, United Kingdom." Both are printed onto the licence when it's issued - without that info it would never be issued in the first place. And it's not a fake, because why would he have a fake licence with his real information on it? It's just an incomplete prop.
Continuity mistake: Throughout the series, the Barbers pull their cars straight up their driveway. But the cars are nearly always shown coming back down the driveway driving forward.
Continuity mistake: When the bad guys create a roadblock with their 2 cars as Hopper drives his girlfriend to her mother's house, the cars stop with one on one side of the yellow line, and the other stops with the steering wheel over the line. The camera angle changes, and now both cars are neatly, evenly positioned, with their engines sitting over the line. (00:02:05)
Factual error: DI Renton is a Metropolitan Police officer 'parachuted' into Kent to solve a big case. This hasn't happened for many decades. Local police forces investigate their own crimes without help from the Met.
Factual error: Thomas holds the Gendarmerie rank of Capitaine (by which he is frequently addressed by his subordinates), and thus should wear three horizontal silver bars on his epaulettes. However, in the only scene where his rank is displayed he instead wears the two chevrons of an ordinary gendarme.
Continuity mistake: The ground is dry and clear throughout the entire episode in all exterior scenes, until the snow covered ground in the background when Duncan is driving to Ellen's house about 2/3 through the episode.
Revealing mistake: When Travis dumps out the heads of the gangs leaders from the case, it is painfully obvious that they are computer generated.
Continuity mistake: Toward the end of the episode, our intrepid heroes stash their large black bags as they run through the market. They run through the market for the next several minutes with only their machine guns. They later board the waiting speedboat but when they disembark, they have their bags.
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.
Episode One - S1-E1
Factual error: In the fairground chase the characters jump over some Heras fencing that wasn't invented until the next decade.
The Surgeon - S1-E7
Continuity mistake: Virdon's head is lying on a pillow looking at Dr. Kira and turns it to his left shoulder as Dr. Kira speaks, but a quick shot back to Virdon and his head is looking at Dr. Kira again.
Funny Money - S1-E10
Factual error: The characters travel to Cyprus where they are seen driving on the right hand side of the road, when in Cyprus they drive on the left.
Factual error: In Massachusetts, Atticus, Leti and George are attacked by the local sheriff and his deputies, who are patrolling the county roads. In Massachusetts, sheriffs run the county jails, but they do not (and did not) handle routine policing, which is the responsibility only of municipal police departments.
Factual error: Possibly a mistake from the novel on which the series is based, but although he later became Bishop of Hereford, St Thomas Cantilupe wasn't baptised in Herefordshire. He came from Buckinghamshire.
Learning Curve: Part 1 - S1-E5
Continuity mistake: When the ship has made it through the plasma jump and is approaching the Universal Library, the images of the Watchers the ship passes by go from being transparent, to solid, and then back to transparent.
Fear and Loathing in Beverly Hills - S2-E8
Continuity mistake: In one part of the scene where Joe has Delilah's iPhone and it's ringing, it shows the call with a green answer button and a red decline button, then, it shows it only with a slide to answer option. (00:53:00 - 00:59:00)
Factual error: Sir John Franklin, Francis Crozier and James Fitzjames all wear a crown over an anchor on their epaulettes, the rank badge for a captain with over three years in rank. This is correct for Franklin and Crozier, but Fitzjames only held the rank of commander, and should therefore only be wearing an anchor on his epaulettes.
Factual error: The provincial police is always described as the Ontario Police Department (OPD) instead of the correct Ontario Provincial Police (OPP).
Factual error: Despite taking place in Massachusetts and many of the cars having Massachusetts license plates, none of the vehicles has the required annual inspection sticker on the lower part of the passenger side of the windshield.
