The X-Files (1993)

Visible crew/equipment: I don't know if this is visible in all formats, but on the newest UK release on DVD, watching in widescreen, it's amazingly obvious. When Mulder recovers from the vampire attack, he gets up from the floor and breaks up a chair to make a stake. There is a shot of his feet as he smashes the legs off and bends to pick up a piece. In the bottom left hand corner of the screen, you can see a crew member's hand carefully and quickly placing a piece of wood on top of the pile for Mulder to pick up.

Continuity: When Mulder is in the Tram car ascending the Mountain, to rescue Scully, he pulls all of the things out of under the top left-hand seat, but when the scene moves to Krycek in the booth, you don't see any of the thing that Mulder threw out.

Visible crew/equipment: A mic boom operator is visible on the left hand side of the screen wearing a white t-shirt, beige shorts, and sneakers. He's carrying the boom mic and following Mulder and Scully. You can see him when Mulder and Scully arrive at the "Church of God with Signs and Wonders" for the first time...when Mulder delivers the line "That's funny, I knew a couple Catholic schoolgirls who were experts at it."

Scully's father and the man Mulder thought was his father were both named William. Mulder's actual father, Cancer Man, was played by William B Davis. Scully and Mulder's son was also named William.

In 2001, The Lone Gunmen were given their own self-titled TV series, The Lone Gunmen.

Whenever the Cigarette Smoking Man smokes on the show, the actor is smoking herbal cigarettes.
