Factual error: As the beginning shows Krypton explode, there is a huge cloud of dust at the remains of the planet that then fades to nothing. Only space dust would not act like that from an entire planet exploding. It acted like dust settling on the ground and just fading away, rather than dissipating into space. (00:01:25)
Factual error: The Marine Colonel in Supergirl played by Eddie McClintock spends all of his time wearing Marine Officer's Dress Blue Bravos. Marine Dress Blues are ceremonial uniforms. On rare occasions, the Charlies or Deltas (no coat) may be worn as a work uniforms (the primary exception to this rareness being recruiters). The full uniform is certainly not worn for day to day work in the field.
Killer With a Long Arm - S1-E4
Factual error: The assassination attempt takes place on Wimbledon Finals Day, yet there seem to be other matches going on at the same time, which doesn't happen when the final's occurring.
Factual error: At Walter's apartment, Annie notices a group of spy novels on his shelf. The "spy novels" are actually six books from the Goosebumps series by R.L. 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: Picard tells his manservant that Laris and him are more needed at the Chateau than with him in space because there's less than a month left before the harvest. Without being privy to the knowledge of a XXIV century agronomist, grapes at the Chateau are grown with traditional methods in a climate that looks reasonably similar to our own. From the establishing shot at the beginning of this episode and what we could see by his walk in the vineyard in the previous, there are no grapes forming, ripening, not even flowers. Hardly the look of a vineyeard close to harvest. (00:07:00 - 00:36:10)
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.
The Corps is Mother, the Corps is Father - S5-E13
Factual error: Bester lifts the blanket covering the bloody corpse of Harris' roommate. The man hasn't been dead long enough for the blood to dry, so there should be blood-transfer on the underside of the blanket - but there's not a spot on it.
Factual error: When the trucker reaches into the bag that's suppose to have his cash with his "bonus", he's bitten by a venomous snake. However, we see the snake and it's a non-venomous king snake.
The Legend of Curtis Ballard - S2-E3
Factual error: In the first flashback scene of Ballard serving a Mormon mission in Lithuania, he laments that he has been on his mission for 18 months and has yet to baptize a single person. In a later flashback scene when he and his companion are visiting the prostitutes, he states that he and his companion are 19 years old and they should be in college, going to parties, getting drunk, getting laid, etc. Instead of serving missions. These scenes take place in 1991, at which time young men did not serve missions for the Mormon church until after they turned 19, so if Ballard had already been on his mission for 18 months, then he should have been at least 20 years old, and closely approaching 21.
Factual error: The Essenes climb Masada bearing the scrolls. Just as Joseph Wiseman is framed solo, a black SUV drives from left-to-right below him on the road.
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)
The Day Danger Walked In - S3-E5
Factual error: Higgins, Thomas, TC and Rick are locked in a freezer. Their barber friend is tapping his horn in "a pattern" Higgins says is Morse code, and announces that he tapped "move back." Not really. I know Morse Code. All I got (along with a few undecipherable things) was TOERT NMU ETM CEA OFJ DER WK. No way that spells "Move Back."
Factual error: At the end of the episode, they say the Bible said he lived to be 110 years old. The Bible says 70.
Factual error: 1-1 A couple of spelling errors. A "community center" in Ceylon, a British colony, using the American instead of the British spelling. And Columbo listed as the capital of Ceylon; it's Colombo.
Factual error: It isn't catering to American tourists (the guests are from all over the globe), but the Posada Angelita Hotel in Mexico has only American flags out front. (00:03:15)
Double Dose - S2-E10
Factual error: Season 2 episode 10 "Double Dose": When Superman snatches Parasite's escape boat and hauls it back to Stryker's, Parasite attempts to blast him with a shotgun found aboard. But somehow the animators appeared unable to decide whether the gun should be a double-barrel or a pump-action type; and building a double-barrel pump gun would be impractical due to additional weight and bulk.
Factual error: Simone is hit by a bus running after her niece. The bus is service number 106, however service 106 is Finsbury Park - Whitechapel and runs nowhere near Horseguards Parade, which is where the scene was filmed. Also the bus is operated by Sullivans Buses, when route 106 is actually operated by Arrivia. The depot code SM (seen on side of bus) is Potters Bar and not AE (Ash Grove) which is the actual depot that operates route 106.
Factual error: Many of the Royal Navy details are completely wrong. The submarine captain's cap badge is not that of the Royal Navy. "Midshipman" Leonard wears the insignia of a chief petty officer. "Officer" (not a naval rank) Neal wears the insignia of a petty officer. "Officer" Shaw wears the insignia of an able rating. The Flag Office Submarines is depicted as a full admiral, whereas in fact he was a rear-admiral and the position no longer exists.
Glorious Five Year Plan - S3-E4
Factual error: The Boys use a Dodge Sprinter to drive around Russia. In Europe and Russia this Sprinter was only sold through Mercedes-Benz.
Factual error: At an eating area, a collector shows a man a computer screen with his daughter in real time and has her call him. She then speaks in the phone and you can see her lips and actions lining up perfectly with the words he is hearing. It would not be this perfectly in sink even in the most optimal of conditions. There is a slight delay between the video from the camera and sending that to the computer being shown. And then there is also a slight delay of the phone single traveling through one phone to the other. These would not line up right and so the father would not see the lips moving exactly with what he hears his daughter saying over the phone.
