Factual error: The series takes place during the 1930s prohibition era. The $50 bill projected on screen is series 1953A with signatures of Ivy Baker Priest and Robert Anderson.
Closely Watched Planes - S4-E3
Factual error: If there really was a hatch leading into mid-air in the airplane bathroom, instead of being soundless like shown, it would be incredibly loud and Max would have noticed. Also, the sudden pressure change would have sucked him out no matter what he did to stop it.
Episode #3.2 - S3-E2
Factual error: The navigation software "What3Words" is featured. Apparently the words "flop, sponge, knee" point to a storage facility in London. In reality, they actually point to somewhere near the city of McGrath, Alaska. "Hunch, bumpy, strut" are also mentioned, which actually point to somewhere near Paraburdoo, a town in Western Australia, definitely not a forest in London as depicted in the episode.
Factual error: The lady goes into the bank with a key for the safe deposit box and they let her into the vault. The box belongs to a Sullivan. They insert the bank key and she inserts hers. For somebody to be allowed access to the vault to any storage box, that person would need to be the owner of that particular box, and they would need to sign a card/log to gain entry. If it's in John Does name, Barb Smith can't just show up with a key and get access. (00:35:00 - 00:36:00)
Episode #1.1 - S1-E1
Factual error: Unlike Christie's novels, there is no explicit statement of the date - the original novel started on the August 8th, which is compatible with what is shown here; Vera is interviewed and the letters are all posted on August 2nd 1939, which would fit. However, there's a problem when Vera changes seats en route to Soldier's island. A passenger is reading the Daily Express, and the headline is from August 29th of that year. Too much time elapsed and it's the end of the Summer while the chat between Emily and Vera implies otherwise; it's also Tuesday but the doctor comments "It's been a long week" when he apologizes at dinner - the weekend feels a more appropriate time for a party and gathering as shown. (00:06:15)
Factual error: The German series is set in 1987 in Berlin before the wall came down. It shows a suitcase going through airport security that wasn't set up until after 2001.
A.K.A Customer Service is Standing By - S3-E4
Factual error: Trish knocks the bad guy into the pool - he sinks to the bottom where Erik can conveniently grab the knife and cut himself free. But bodies don't sink - he should be floating on the surface, still out of reach.
Episode #1.1 - S1-E1
Factual error: The series is set in 1933, as the initial captions show. Yet the locomotive pulling the Orient Express is a JNR Class C58: the C58 series was built starting from 1938 (C58 239 used here is from 1940).
Factual error: Percy Bysshe Shelley's father was a baronet, not a peer. He was Sir Timothy Shelley, not Lord Shelley as he is referred to here.
Factual error: The FBI agent introduces himself and says "Mike Weston - I did my thesis on Joe Carol at the academy." FBI agents are required to have a university degree, but they don't write thesis' at the academy. A person is either in a university or at Quantico getting trained. They are not writing papers at Quantico. They need the degree beforehand to get in. (00:10:30 - 00:11:30)
Episode One - S2-E1
Factual error: During this episode, Vincent is remanded to prison for suspected murder. At one scene he is seen working on the wing. Remand prisoners are not expected or allowed to carry out work duties in British Prisons.
Factual error: ACC Pat Gallan wears the ribbon of the Queen Elizabeth II Diamond Jubilee Medal. The medal was issued in 2012. Her medals would be correct for 2017 when the series was made, but not 2007 when it is set.
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.
Factual error: When they deliver the drug and guns to the reservation, the car James is driving, has an Arizona license plate on the front of the car. Arizona does not issue plates for the front, only one plate for the back of the car.
Factual error: The shoulder patch on the U.S. customs and Border Protection officer's uniform is wrong. The real patch doesn't state Dept of Customs and Border Protection and United States Homeland Security in a smaller circle on the patch. The real patch just states U.S. Customs and Border Protection - U.S. Customs and Border Protection is not a department. Also, the officer doesn't have a name tag on over the right pocket. (00:04:00)
Factual error: 19 1/2 minutes in. They pull over a car and run the plate. Malloy tells the driver the car is registered to a Volkswagen. He should have said the plate is registered.
Dial Margaret for Murder - S2-E4
Factual error: In Series 2 Episode 4 (Dial Margaret for Murder), Allison listens to Dick Frank's heart. She has her stethoscope in her ears backwards. As a physician, she would never do that.
Factual error: Donna jumps off the bridge (which is relatively low down), into shallow water. She then narrowly avoids being hit by a huge ocean liner. There's no way such a huge ship would be in such shallow water - for starters, it couldn't cross under the bridge, being far too big. (00:03:12)
Factual error: Detective Chief Superintendent Kier Pritchard wears silver tabs on his uniform collar. These are only worn by Assistant Chief Constables and above. Detectives almost never wear uniform in any case.
Factual error: The only person ever addressed as "Sir" is the brigadier, and then only occasionally. No other officers ever seem to be addressed in this way.
