The X Files 105 The Jersey Devil Facts, Trivia, Goofs

• It was David Duchovny that suggested to Chris Carter that Claire Stansfield should play The Jersey Devil. Duchovny and Stansfield had met earlier while filming The Bounty Hunter (1992) together.
• This is the first episode to allude to Mulder's obsession with pornography ("Anti-gravity is right").
• In folklore, the Jersey Devil is usually portrayed as a human-sized vampire bat with a long face. This model is not used in this version.
• Another reference to The Silence of the Lambs is used in this episode, this time by Detective Thompson, whilst he is talking to Mulder, after Mulder's arrest, he says, "I've got a perpetrator out there, whether it's Hannibal the cannibal or Elmer Fudd, I've got a job, to protect people".
• This episode takes place in 1947 and 1993.
• The drawing of the female "devil" that Mulder carries with him is a representation of the Northern California Bigfoot captured on 16mm film by Roger Patterson in 1967. It's the first filmed evidence made public, and many still consider it the best evidence of the Bigfoot phenomenon. 
• Wayne Tippit is a distant relative of Dallas police officer J.D. Tippit who was murdered by Lee Harvey Oswald after President John F. Kennedy's assassination in Dallas Texas in November 1963. Wayne Tippit also had a small role as FBI Agent Frank in the 1991 film "JFK". Series star David Duchovny later played J.D. Tippit in the 1992 film "Ruby". 
• Late in the episode, Mulder requests a car while at FBI headquarters. Attached to the clerks desk is a "Baby Blues" comic strip from September 27, 1992. 
• There may be a bit of an inside joke with one of the characters. The Forest Ranger's name is Peter Brullet (pronounced "broo-LAY,") which sounds close to author Pierre Boulle. Similar to the focus of this episode, Boulle wrote a book describing human-like homonoids called "Planet of the Apes." 

spoilers

• In the final scene, the man and his son hiking in 1993 are played by the same actors, Bill Dow and Lachlan Murdoch, who played the man killed by one of the Jersey Devils in 1947 and his son in the opening scene.
• If the final verdict is correct that the "devils" are just humans who were never taught to live as civilized people, then this is the first X-Files episode with no fantasy or science fiction elements.
• This and Never Again (1997) are the only times in the entire original series in which Scully has a date. She will have another one in the revitalized series season 10 opener, My Struggle (2015).
• This is the first episode in which Mulder goes to jail.
• It is revealed that Scully has a godson, but this info is never used again in the remaining 10 seasons.

• When Mulder is looking through the phone book, his finger rests on the listing for the New Jersey State Parks office. The listing includes a phone number to call for park hours, with a note stating "Thru Labour Day Only." American English drops the "u" from words like "labor."
• When Mulder and Scully first walk across the office to acquire a car, the cameraman walks into the edge of a desk and the camera noticeably jolts to the left. A second later the offending desk is in shot.
