Starring: Robert Patrick, David Duchovny, Annabeth Gish, Gillian Anderson, Mitch Pileggi
Factual error: When Mulder is walking out of the cabin in Spender's uniform, the soldiers try to stop him. This is impossible since he is an officer (a lieutenant judging from the shoulder-straps) and they are privates, so they cannot give him orders. The only thing they can do in this situation is to salute him. (00:08:40)
Factual error: The alternate version of Scully is identified as an OSS agent, but the OSS did not exist in 1939. (00:34:35)
Clyde Bruckman's Final Repose - S3-E4
Continuity mistake: Clyde Bruckman commits suicide by placing a plastic bag over his head until he asphyxiates. However, when Mulder and Scully first discover him you can see in the shot just before Scully holds his hands that there is no plastic bag around his head (may only be visible in widescreen format). (00:42:55)
Deep Throat - S1-E2
Mulder: They're here, aren't they?
Deep Throat: Mr Mulder, they've been here for a long, long time. (00:49:58)
Trivia: The initial footage of the episode was taken from the movie Airport 1975 (a Columbia Airlines jumbo jet). (00:00:01)
Chosen answer: Yes.
