Factual error: Jayne doesn't need the suit to fire his gun, because ammunition contains an oxidizer that would allow it to be fired even without oxygen present.
Suggested correction: From a different perspective it's not a factual error. Because Jane shot multiple bullets. It means the gun still can be shot after the space suit case got pierced from the first bullet. So it's a possibility that the characters thought wrong (even though it's a bit silly for space travellers to not know this fact but doesn't mean it won't happen).
Factual error: When Nasedo kidnaps Liz, he stops in a gas station to leave the FBI another clue. As he is pulling into the station, the sign above the gas pumps misspells the word "brakes" as "breaks."
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; its type switches from one scene segment to another.
Factual error: Early in the episode, it is mentioned that Mrs. Faulkner's husband flew an F-16 fighter. Later, during Mrs. Faulkner's speech after her meeting with Anna, a picture of her husband is shown. He is wearing a Navy Dress Blue uniform. The Navy does not fly F-16s. In the US military, they are used exclusively by the Air Force.
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.
Factual error: When Jim is watching the guy about to be blown up, the reflection in the binocular lens is the same as we just saw, when it should be a reversed image.
Trace Decay - S1-E8
Factual error: When the armed party comes into town to steal the safe in the bar, the leader points a repeating rifle at a victim on the ground and shoots. When he fires a used cartridge flies from the gun. Repeating rifles do not eject cartridges when they are fired. Automatic weapons eject a spent cartridge when fired. Repeating rifles only eject the cartridge when the lever is wrenched. (00:32:20)
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: Darien sets up a tripod and videotapes himself leaving a message for the Agency. When the tape is played back later, the camera can be seen to have both zoomed in and panned to follow his movements, even though no one was there to make those adjustments. (00:30:30)
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.
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 map of the western United States shown during the weather report at the start of the episode shows some states drawn incorrectly. Idaho's entire western border is a straight line, whereas in real life, Oregon has a horn-shaped indentation on its northeastern border that it shares with Idaho. Idaho also looks like a crude staircase, with the southwestern border of Montana going down to central Wyoming, whereas that area in real life is around the northwestern part of Wyoming.
Factual error: Even though the show is called "Samurai Jack", Jack isn't really a samurai. The correct title for him would be a Ronin as a Ronin loses their master if their master dies or loses favor with their master and also has no home anywhere. Jack has these attributes. He has no master and no home.
Suggested correction: Nor is his name really Jack. "Jack", and thus "Samurai Jack", is just an alias that the prince takes. It's not meant to be his title or rank. Just like Cowboy Jack wasn't actually a cowboy.
Factual error: Mary gives Dick directions to press Command-Q to close something. As Dick is using a Compaq computer which would be running Windows, he would not have a Command key and would instead have a Control key (which he actually is pressing) as the Command key exists only on Apple Macintosh computers. Ctrl+Q on a Windows machine doesn't do anything. (00:09:10)
Factual error: The Robinsons exceeded the speed of light due to impurities in chemical rocket fuel. No chemical rocket fuel comes remotely close to the energy content needed to even approach the speed of light. That would require exotic fuels like antimatter. By Einstein's theory of Special Relativity it is impossible to exceed the speed of light with any form of rocket propulsion. Faster than light travel and time travel might be possible with the warped spacetime of Einstein's general theory of relativity and phenomena such as wormholes. For plausibility the opening scene should have been an encounter with a wormhole.
Factual error: In the opening sequences of the show, B-17s are over the Ruhr in August 1944, and yet they're being attacked by nothing but yellow-nosed BF-109E's. The yellow nose was discontinued at about the end of the Battle of Britain, and the "E" model was discontinued even before that.
Factual error: When Rich and Laura are searching for drug information from the 1960s, they visit the US Patent Office website; under the heading "SSRIs", is displayed "Selecttive Serotonin Reuptake Inhibitors" - with the double-t spelling error. (00:15:25)
A Ghost for Scotland Yard - S2-E8
Factual error: Bearing in mind the episode takes place in London, Sir Arthur MacCready is driving his Rolls Royce. The car has the steering wheel on the left hand side. A true British Rolls Royce would have the steering wheel on the right side. This is a Hollywood Rolls Royce.
Factual error: When we see the SPV escaping from the Culver Atomic Centre, it is night time. However, when we see Number 3 Tracking Vehicle, it has changed back to daytime.
Factual error: The story takes place in Galveston, Texas. The geographical area is flat, but if you look closely near the last hulk out, there are mountains in the background.
