The original concept for this episode involved Mulder and Scully finding themselves trapped in a TV show.
Both William Gibson and Tom Maddox were big fans of The Lone Gunmen so they deliberately wrote an episode that involved them.
It won 2 Emmy Awards for Outstanding Sound Mixing for a Drama Series and Outstanding Special Visual Effects for a Series.
All the special effects needed for the episode meant the episode nearly went over budget. The production crew ended up borrowing different virtual game layouts from video game companies to cut costs.
