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.
