Chapter Two: The Weirdo on Maple Street - S1-E2
Factual error: When Chief Hopper and his fellow patrolman are standing over the lake, Hopper has a radio on his belt. The radio is a modern Motorola walkie talkie and at least a decade newer than it should be.
Factual error: In order to take delivery of the demon baby, Crowley meets Hastur and Ligur - two fellow demons - in a church graveyard, but later we find that demons cannot step on to consecrated ground without suffering extreme discomfort. Church graveyards are always on consecrated ground.
Factual error: Sgt. Carter is wearing a plain belt buckle with his dress blues uniform. Since Sgt. Carter is Gunnery Sgt, he is a staff NCO so his buckle should have the USMC emblem on the buckle. (00:24:00)
It's Not Easy Being Green - S5-E16
Factual error: Boomhauer's car, Ms. Sally, has a Texas flag license plate on it. These plates were not issued until 1992, but Ms. Sally was driven into the quarry in the late 70's or early 80's.
The One With The Hypnosis Tape - S3-E18
Factual error: When Pete takes Monica to Rome for the date this would have been impossible as Rome is 6 hours ahead of New York and at least 4/5 hours travel time, assuming they went by Concorde (double that otherwise). They would have had to have left New York early in the morning to make dinner for 8/9 pm in Rome.
Thanksgiving - S1-E9
Factual error: The scene where Kitty is making peanut butter celery for Thanksgiving appetizers; she is using Skippy brand peanut butter and the packaging is not from the 70's, it's the current packaging. (00:05:10 - 00:06:05)
The Beautiful Day in the Neighborhood - S5-E4
Factual error: Near the end, the gang is using Luminol to check for blood on neighbourhood signs. Luminol won't work in broad daylight, they should have used a blue light filtering lens to enhance its visibility.
Factual error: Tom Keen watches an arms deal. The supposedly German plates of the BMW read "DD17-36F9." This, however, is not a possible combination in Germany, as there would not be numbers in the first half, nor a letter after a number in the second part. [exceptions from the first being the most important officials' cars like the federal president's, but even then the latter applies]. Furthermore, no more than 4 numbers can be used, except for in police and military vehicles (which also never have a letter after a number, and start "Y" for military, or "DD-Q" for Dresden police). "DD-F1736" would have been a correct plate for the town of Dresden, for example. (00:23:15)
Factual error: Laura Ingalls Wilder was born in 1867. Ralph Waldo Emerson died in 1882, which means she was at the maximum 15-16 years old (and already married) in order to meet him IF he were to appear in 1882 which is not possible because: The problems with his memory had become embarrassing to Emerson, and he ceased his public appearances by 1879 (according to wikipedia).
The Royale - S2-E12
Factual error: 30 seconds in Geordi says: 'surface temperature -291 degrees Celsius'. (The scale only goes down to -273.15 which is absolute zero). (00:00:30)
The People vs. the Fonz - S11-E11
Factual error: When the Cunninghams are talking about Fonz's trial, Mr. Cunningham can be seen wearing a digital watch. Digital watches didn't exist in the 50's.
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)
Factual error: A character in the episode has invented denim, but denim was invented in 1873 and was being used widely up to the time period of the series, which is set in 1893.
Suggested correction: The entire series was set in an alternate history of sorts, so most, if not all, historical "inaccuracies" cannot be regarded as mistakes.
Factual error: The naval captain in this episode has a military mustache as prescribed by army regulations. The Royal Navy regulations, however, prohibited separate mustaches and beards - if facial hair was worn, a "full set" of beard and mustache with the beard joined to the mustache was mandatory, and that to be grown to the commanding officer's satisfaction within six weeks.
Factual error: In scenes from the oil rig there are shots that show the shore line. This oil rig is supposed to be offshore of Louisiana. However, mountains can be seen in the shots of the shoreline. There are no mountains in Louisiana.
The Suitcase - S4-E7
Factual error: At the beginning of the episode, the male employees are all discussing James Bond. It is mentioned that 'James Bond goes underwater, he met a girl underwater'. This refers to the plot of the movie 'Thunderball' (it does not occur in the Thunderball novel, nor any novel or film prior to this). The main plot of this episode centres around the Sonny Liston VS Cassius Clay fight in May 1965, and 'Thunderball' was not released until December of that year.
Thorpe Park - S1-E3
Factual error: The same number plate can be seen on two different vehicles in this episode. The registration M483LTH can be seen on the hearse and then on Simon's car when parking. No two vehicles in the UK will ever share a number plate. (00:11:10 - 00:12:30)
Factual error: Wanda's father opens his briefcase of DVDs and one of them is Malcolm in the Middle. But the bomb that killed him fell in 1999, and Malcolm in the Middle didn't start airing until 2000.
Factual error: Mulder refers to a Royal Navy vessel that sailed from Leeds. No large ship can sail from there - it is at least 50 miles from the coast.
Archer Vice: Southbound and Down - S5-E5
Factual error: When the bikers are chasing the bus, one of them crashes into the "Now Leaving Texarkana" sign. However, shortly before this, we see Cyril crashing into the sign reading "Austin. 105 miles." Texarkana is almost 350 miles from Austin.
Suggested correction: But it is a satanic church so Crowley can step in it.
There is nothing in The Book or the film to suggest that the graveyard is part of a "satanic church."
The church is run by Satanic nuns who are orchestrating the entire plan to switch babies.
No, it is not. Crowley has to drive for a considerable distance from the church to the convent in order to deliver baby Adam to the satanic nuns. They have nothing to do with it.
