The X-Files ( 1993 )

Factual error: Scully makes a reference to an F.B.I. field office in Kansas City, however, no such office existed at the time of this episode. (00:13:10)

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)

Other mistake: Unlike Mr Chaco, who has the brace clamped around his neck, Scully is clamped around the top of her head, which is a quite irrational way of executing a person, because the clamp does not serve as a stabilizer. In fact, in this arrangement, Scully is not fixed to the stand at all. (00:38:15)

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.

Other mistake: Immediately after a shot has been heard, Mulder, who is in flat #42, grabs his gun and rushes through the corridor passing by flat #47, which means he is still on the same floor. Within 10 seconds after the shot, the next-door lady is already aware of the crime. Not mentioning that 2 seconds later two policemen arrive at the scene. (00:07:21)

Character mistake: Mulder asks Scully about "the fourth commandment about obeying the Sabbath, the part when God made heaven and Earth " However, Scully as a Catholic should know that this is the third commandment for Catholics. This is also an indirect indication that Mulder was raised in Jewish religion. (00:09:25)

Visible crew/equipment: As Scully stands up to leave at the offices of the Navajo Nation, the reflection of a boom mike moving in one of the picture frames on the wall can be seen. (00:19:40)

Continuity mistake: When the military man approaches the Cancer Man we can see at the background the helicopter's left-hand side. When they move towards the helicopter, now closer to them, we see its right-hand side. (00:40:14)

Factual error: It is completely impossible the Thinker has made a digital copy that cannot be duplicated.

The Blessing Way (2) - S3-E1

Continuity mistake: When Mulder experiences his near-death trance state his body is lying, apparently lifeless, in a star spangled sky. As the camera tracks in on him the toes on his right foot twitch, just after Deep Throat begins to speak. The foliage covering his chest also changes position between shots. In the wide shot he is covered up to the armpits. But the first close up shows his chest is exposed. Then in later close ups it is covered again. (00:14:25)

The Blessing Way (2) - S3-E1

Plot hole: Mulder is pulled from the escape hole previously dug by the hybrid aliens to escape the train car. When they pull him out they show alien bodies remaining in the hole. Mulder never revisits the train car despite knowing there's a high probability of finding hard evidence, in this case some actual bodies. There's no way Mulder would just assume there's no evidence remaining there and not go have a look for himself. Same goes for Cancerman who thought he had destroyed the evidence.

Factual error: In the footage's right-hand side, we can see the Church of the Covenant's facade, which is located at East 42nd St. New York. However, the subtitle erroneously states 46th St. (00:09:40)

Other mistake: The heavy rain falls and bangs on the greenhouse roof, although Mulder and Scully are completely dry, even though they carry no umbrella with them. (00:10:20)

Factual error: Mulder tells Scully that he is trying 27828 and it is not working. It is not surprising that it is not working, because the Napier constant is not 27828, it is 271828. Plus they somehow they know how many digits from this constant should be entered on the keyboards. (00:15:55)

Visible crew/equipment: When Mulder and Scully enter the abandoned mine through a doorway, the viewer can see at right in the distance a number of people sitting on a wall, and one crouching in front of the wall with what looks like a dog. They are sitting still, but there is still movement there. (00:16:00)

Continuity mistake: In the mine with the medical records we see Samantha's file. In the season 1 episode "Conduit" we see the X-File Mulder opened on her. In the previous episode she is listed as Samantha T. Mulder and her birth date is 1/22/64. Here we see her name as Samantha Ann Mulder and her birth date as 11/21/65. (00:20:40)

Factual error: Skinner says that he could not print the file. However, Scully somehow must have been able to print it in order to give a hard copy to Albert Holsteen for his translation. (00:26:35)
