Production
Due to the pending release of The X-Files feature film, this was the first season where the course of the season was planned in advance, as it had to set up for the film. Originally, the season was supposed to be the show's last. In this manner, the finale was originally supposed to have segued the television series into a movie franchise. David Duchovny explained, "we were saying, 'Okay, we're going to do five. We'll get out of here at five.' And then five came around, and no one was going anywhere." The series proved to be so lucrative for Fox that two additional seasons were ordered.
