Factual error: A thief has stolen 75 million dollars. He runs out with two large duffel bags. All US bills weigh a single gram. This means that $1,000,000 in $100 bills - the largest bills in circulation - weigh around 10 kilograms, or a little over 22 pounds. $75 million would be 1,650 pounds. No way this could be carried in two duffel bags.
Factual error: At O'Neil's retirement party, '2-Way' by Lil Romeo is playing while one of the characters is dancing. This scene is set in the summer of 2001, the song was released in April 2002, nearly a year after the retirement party took place.
Episode #1.1 - S1-E1
Factual error: The American flag shown waving outside the White House is the current present-day flag with 50 stars. From 1896 to 1908, (the time period that this show is set in) the US flag only had 45 stars as Oklahoma, New Mexico, Nebraska, Alaska and Hawaii were not recognised as states in that time period. The flag did not have 50 stars until 1960. (00:04:30)
Episode #1.1 - S1-E1
Factual error: This is set in 1933. When the killer comes back to his lodgings in episode 1, Lily on the stairs is humming "Somewhere over the rainbow", which was written for The Wizard of Oz in 1939. She also happens to wear bright red shoes, which feels like yet another Wizard of Oz reference. Interesting enough, the subtitles say that she is humming a different song, "Night and day" which she openly sings throughout the series and was already a hit in 1932. (00:44:10)
Factual error: Jamie is looking at his birth father's Montana State Prison inmate identification sheet. On the sheet, it lists his Social Security Number (SSN) as 4142-77-89332. However, in the United States, an SSN is a nine-digit number. (00:25:07)
Greenlight - S1-E16
Factual error: Captain Anderson pulls a suspect underwater and shoots him. There's a bright, yellow flash under the water. In reality, this wouldn't happen, only a large amount of bubbles would appear, but no flash.
Factual error: The Saturn in the show is an Ion which stopped production in March of 2007. Therefore, it couldn't be a silver 2009 Saturn they were looking for.
Factual error: When Starfire gets out of the totalled car, there is a road sign visible. It is a settlement exit sign, denoting the exit of Königsstetten and Zeiselmauer as next settlement ahead. Obviously the makers tried to be extra thorough nailing down their "outside Vienna" location. They started OK - both Königsstetten and Zeiselmauer actually ARE outside Vienna - but then they completely botched it: Not only did they use a German black-on-yellow "StVO Zeichen 331" instead of the Austrian "StVO Hinweiszeichen 17b" which has black writing on a white base with a blue rim and doesn't list the next settlement, but they also put 852km as the distance to the next settlement, which is more than the length of Austria west to east. The real distance is 3.8km.
Nothing Seems the Same - S4-E1
Factual error: Nothing Seems the Same: The bus has Seattle Department of Corrections printed on the side. There is no Seattle Department of Corrections. Corrections in Seattle are done by King County Jail or Washington State Department of Corrections. (00:05:07)
Episode #1.6 - S1-E6
Factual error: When Commander Anne Sampson appears in her body armour she wears the rank insignia only worn by the Commissioner (a crown over a pip over crossed tipstaves in a wreath) instead of that worn by her own rank of Commander (crossed tipstaves in a wreath). She has apparently been promoted four ranks.
Factual error: Luka's military officer cap isn't a Russian cap, it is a Hungarian police cap. The Russian cap is bigger.
The Strangers Across the Street - S1-E2
Factual error: Ed Wiggins and his media liaison are taken by surprise when they see the "Sinful Messiah" article in the Waco Tribune-Herald. The ATF had actually been aware of the article and tried to stop its publication.
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: During Pray Tell's visit with his birth family in Pittsburgh, Jada wants to make sure his final wishes are carried out and presents him with a power of attorney document to sign during lunch at a restaurant. He signs it with only Jada present. In Pennsylvania, to be legal a power of attorney needs to be signed in the presence of two witnesses other than the person being granted power. (01:00:10)
Making Dead Things Look Nice - S4-E7
Factual error: When Carolyn leaves the hotel and gets into the taxi, you can briefly spot the license plate. In Austria, the first part has only one or two letters; here it is three letters. For Salzburg, it should be S or SL.
Factual error: Sergeant Bumpher never wears any rank insignia. He appears to just be a constable.
Factual error: After Dr. Austin directs the anesthesiologist to urgently start phentolamine intravenously to address the patient's hypertensive crisis on the operating room table, the anesthesiologist is seen quickly rolling the clamp on the line, purportedly to make it run faster. The clamp however is being rolled in the direction to close off line's flow. (00:20:20)
Factual error: Johnny gets a personalized license plate that reads "cobrakai", which is 8 characters. California license plates only allow 7 characters.
