Schizogeny - S5-E9
Revealing mistake: A heavy rain is falling but there is no sign of it on Mulder and Scully. (00:32:00)
Continuity mistake: When the Lone Gunmen speak with Susanne Modeski, in the background there are some cars parked in front of the Stadium Inn. However, just seconds after, when the telephone rings, there is a white truck parked at the entrance. Later on, the cars are back again. (00:38:55)
Continuity mistake: During and just after the Mulder's seizure, when Scully's face is shown, it is at the level of a standing person which suggests that both agents are standing, but in the next shot Mulder and Scully are crouching. (00:31:35)
Other mistake: When examining the bag via X-ray at the airport, Mulder communicates to Scully that he sees three circular pieces inside, however only one circular piece is visible inside the superstructure. (00:31:20)
Other mistake: The landing plane is shown in a incorrect scale - it's too small compared to the sedans chasing Mulder and Scully. (00:32:30)
Factual error: Gonzales shot himself in the forehead but he's got the back of his head intact - no exit wound. (00:27:40)
Other mistake: Sergeant Louis Frish had not enough time to walk down from the air traffic control tower to meet the agents since he was on the top of it when Mulder and Scully drive up to the tower - two persons can be seen on the top of the tower. (00:21:45)
Factual error: In the background the full moon is visible and it's early morning (approx. 6:00 AM). However, at the start of the episode we see the full moon at night (approx. 19:50). Due to the fact that these are consecutive days, this situation is impossible from an astronomic point of view. (00:14:35)
Factual error: The last number on the truck's license plate is "77." On Russian plates the last two/three digits stand for a registration place. "77" is a number for Moscow, but the Gulag is located in Krasnoyarsk region, so the number should be different. Besides, the format of the plate (LDDDDL|DD) is incorrect - the correct one is LDDDLL|DD (L - letter, D - digit). (00:11:05)
Character mistake: Vassily Peskov speaks Russian with a strong accent. This is because the actor who plays Peskov (Jan Rubes) was from former Czechoslovakia.
Tunguska (1) - S4-E8
Factual error: This is probably the first time in history of civilized mankind that a person with a diplomatic visa is full-body-cavity searched, not to mention the illegal opening of the diplomatic bag. (00:04:05)
Musings of a Cigarette-Smoking Man - S4-E7
Character mistake: Ramón Mercader did not assassinate Leon Trotsky with an ice pick, as Frohike claims, but with an ice axe. (00:03:00)
Other mistake: When the attackers leave the sheriff's house they walk and run as normal people, although in previous scenes they walk in a clumsy way. The same in the scene with chasing pigs. (00:23:00)
Continuity mistake: In The Beginning, when the Bounty Hunter gets out of his car, Jeremiah Smith says nothing. However, in the same scene at 42:08 in the "Talitha Cumi" episode, Jeremiah says "He is here to kill me." (00:00:05)
The Goldberg Variation - S7-E6
Revealing mistake: Henry's right eye is glass, yet its pupil dilates and constricts respective to the amount of light to which it's exposed.
Continuity mistake: Malcolm Wiggins stabs Alfred Fellig in the back three times, including once in the middle of his back to the right of his spine. However, when Scully is examining Fellig's back later in the episode, he has at least six stab wounds, and all of them are around his shoulder blades. (00:13:30 - 00:18:00)
Visible crew/equipment: When Mulder is driving away from the gas station, crew members as well as some filming equipment can be seen reflected in the car's body. Mulder is in a pretty desolate area, so seeing people reflected in the car's body would in all likelihood be crew members and not random citizens. (00:28:30)
Revealing mistake: When Mulder - whilst trapped in the body of Morris Fletcher - is doing various poses in front of the mirror, several of his movements and the corresponding movements from the realized reflection of Morris Fletcher are slightly out of sync with each other.
Kitsunegari - S5-E8
Revealing mistake: When Scully pries open the mouth of the man who died from being forced to ingest paint, his eyes twitch. (00:13:50)
Chosen answer: Yes.
