Factual error: On the map behind the colonel during the first scene, Iceland is labelled as being under Nazi control. This is incorrect, as the British were in control of the country during the whole of the war. (00:05:10)
Friends in High Places - S10-E8
Factual error: Police Officer Troy was taken into a room by Sgt Regan to be interviewed. He has one Sgt stripe on one sleeve. He's a police officer, not a Sgt.

Pua a'e la ka uwahi o ka moe - S9-E7
Factual error: A 1932 haulage receipt is shown on screen. It says Hawaii, HI. There was no such abbreviation used for Hawaii until June 1963. The territory was spelled out in full. In June 1963 it was HAW, and then changed to HI in October 1963 with the advent of ZIP codes. (00:38:50)
Factual error: Scenes were obviously not filmed in London, more like New England. The vehicle registrations are the right colour, but wrong format.
Factual error: One of the naked female dancers at the party has breast implants. Although some forms of plastic surgery were known to the Romans, breast augmentation was not one of them. If you want to check for yourself she appears just after the masked dwarf moves through the shot.
Factual error: Will's hospital chart states he is taking Warfarin and Coumadin. These are both the same drug to prevent blood clots. He would not be on both. (00:31:50)

Stein, The Day My Butt Went Psycho by Andy Griffiths, four books from Lemony Snicket's A Series of Unfortunate Events, and the British covered edition of Harry Potter and the Prisoner of Azkaban by J. K. Rowling. (00:18:30)
Factual error: When J.J. first discovers his powers and understands math, the parabola "seen" on the board is wrong for the given equation and it's different than what J.J. actually ends up drawing, which seems more like the right answer.
Factual error: The show is supposed to be taking place in NYC, however its clear by the shooting locations that its shot in Toronto. This can also be seen very by the various signs throughout the city that are not found in the US and are very Canadian in nature, such as the Do Not Enter and One Way.
Factual error: The Merchant Navy rank insignia is very poorly researched. Each officer seems to have a different style of insignia, despite working for the same company and they incorrectly wear rank insignia on the shoulders of their blue uniforms as well as the cuffs. The main character, Junior Third Officer Mortimer, wears a bizarre mix of insignia, apparently consisting of a Royal Navy petty officer's sleeve badge, a Royal Navy chief petty officer's cuff buttons, and a rank badge of three inverted chevrons on his shoulder boards that doesn't seem to resemble anything from reality. In reality, he should simply wear a single cuff ring (or shoulder bar in white uniform).
Factual error: The operator that receives the 911 call only sends the police, when in actuality if a caller is silent during their call, the operator has to send out all emergency services.
Episode #4.4 - S4-E4

The Girlfriend Experience - S3-E8
Factual error: The group set up a sting for prostitution/solicitation, even though it isn't illegal in Canada. The unnamed city they patrol is Canadian, established in the "sister cities" they name, plus often referring to Rochester and New York as "across the border. As for prostitution, the only two times its illegal for adults in Canada is public solicitation (street walking) which doesn't apply for websites, or in running bawdy (cat) houses, neither of which apply here.
Factual error: When Walter Goggins fires a LAW at the church from next to the vehicle, the back-blast from the rocket would have shattered the car's windows, and flying glass fragments would likely have injured the occupant. The show depicts neither outcome.
Factual error: The wedding is at a Christian church preformed by a Christian minister, but at a Christian wedding the groom stands on the Minister's left side and the bride on his right. The way Ryan and Cate stand is the way that the bridal party stands at a Jewish wedding.
