The X-Files

Show generally

Factual error: A number of episodes show trolleybuses operating in American cities that do not use them (including Washington). Vancouver, where the series was filmed, however, does use them.

Space - S1-E9

Factual error: The local Pasadena station code is WXDL, however it should start with a K not a W. (00:00:05)

Space - S1-E9

Factual error: According to the NASA space shuttle launch countdown procedure, the close-out crew retreats to fallback area in the "T-3 hours and counting" phase. The members of the crew are the last persons who leave the launch pad at least 20 minutes before liftoff. However, during the close-up take of the main engines, when the ground control says "All systems go for APU start", we can see two members of the ground personnel in orange suits near the engines. (00:12:40)

Lazarus - S1-E15

Factual error: When Mulder gives Scully the birthday card, she says that he is two months early. Given that Scully's birthday is on 23 February, the time of the episode should be sometime near Christmas. However, through the whole episode, there is no sign of Christmas time (not a single Christmas tree, no Christmas decorations, etc). (00:19:35)

Roland - S1-E23

Factual error: At the crime scene where Roland killed one of the professors by dunking his head in liquid nitrogen and dropped him on the floor, someone has drawn an outline of the dead prof's body and all the bits his head broke into when Roland dropped him. This outline-drawing doesn't happen in life because it interferes with the crime scene, it's a popular myth.

Little Green Men - S2-E1

Factual error: The Arecibo Radio Telescope is abandoned when Mulder goes there. However, after SETI was cancelled, the telescope was still used for other things. (00:16:50)

The Host - S2-E2

Factual error: Scully reads to Mulder from a book all about flukes (Trematodes). However, the information she is quoting is wrong. She states that flukes or flatworms have a "scolex" with hooks and suckers. These are actually the distinguishing characteristic of cestodes (tapeworms). Trematodes have no scolex and definitely no hooks. (00:17:30)

Ascension (2) - S2-E6

Factual error: It's quite strange that only after Mulder looks into the ashtray he realizes that the Smoking Man has been in the car. Mulder should smell the scent of cigarettes immediately after entering the car, especially if he is a non-smoker. (00:36:05)

Die Hand die Verletzt - S2-E14

Factual error: Mulder sees water going down the drain counterclockwise and says something is up since all water in the northern hemisphere drains clockwise. This is not true. Water can drain in both directions in both hemispheres. Things like convection currents, basin design, and residual swirl from filling the sink have a much greater influence. You would have to drain a small ocean to see the Coriolis effect, or use specially-designed test apparatus. See http://www.snopes.com/science/coriolis.htm and http://www.physics.ohio-state.edu/~dvandom/Edu/newcor.html (scroll down to *5.2. Water Going The Wrong Way Down The Sink* near the bottom of the page).

End Game (2) - S2-E17

Factual error: In the opening sequence, we see a nuclear attack submarine beneath the ice in the Arctic Ocean. When the captain orders the ship to surface, one of the crewmen mutters, "Surface to what? We're under 32 feet of glacial ice!" Except that they're not under "glacial ice," they're under Arctic sea ice, which ranges from about 6 feet thick in the summer to about 15 feet thick in the winter.

Dod Kalm - S2-E19

Factual error: Mulder mentions the USS Eldridge as disappearing from Philadelphia (and later reappearing in Norfolk) "nine months after Roswell", i.e., May 1948. In fact, the supposed incident took place much earlier - in February 1943, according to almost all reliable sources. (00:06:50)

Our Town - S2-E24

Factual error: The townspeople contracted Creutzfeldt-Jakob disease (CJD) from the bodies they consumed and it showed up in the brain tissue within a matter of weeks. However, this extremely rare disease takes several years to even be detectable. (00:18:55)

Our Town - S2-E24

Factual error: Mulder says that the events occur near I-10, however, I-10 is nearly 200 miles south of Arkansas's border in southern Louisiana.

More trivia for The X-Files

Show generally

Question: In a vast majority of the episodes, whenever Mulder and Scully investigate some mysterious or paranormal phenomenon, Mulder believes that some unknown force is responsible but Scully always has a rational explanation for what is happening. In other episodes, when Scully herself is caught up in something mysterious, she is the believer but Mulder is the skeptic. In those episodes, why would Mulder be skeptical about an unexplained phenomenon considering that he a was witness to his own sisters abduction and he saw many strange things that defied explanation while working for the F.B.I.?

Answer: As he stated many times throughout the series, Mulder needed Scully to be sober and skeptical. Whenever Scully's skepticism wavered and she started questioning her own rationality, Mulder would try to restore her sense of skepticism, because he needed her to be clear-thinking.

Charles Austin Miller

Answer: A variety of reasons. Just because Scully saw something unusual does not mean that it was. Mulder always needs concrete proof before he'll believe there's some otherworldly explanation for unexplained phenomena. He's too experienced to take a novice's explanation as fact. It is also a plot by device by the writers to switch the tables on the characters to make it more interesting and to let viewers see another side of their relationship.
