Unlike the first film, the plot of The X-Files: I Want to Believe does not focus on the series' ongoing extraterrestrial-based "mytharc" and instead works as a standalone thriller–horror story.

While Walter Skinner (Mitch Pileggi) makes a notable appearance, John Doggett (Robert Patrick) and Monica Reyes (Annabeth Gish) are absent from the film.

During a July 2013 panel discussion at San Diego Comic-Con hosted by TV Guide, both Anderson and Duchovny expressed willingness to do a third feature film, but Carter was more reserved at the idea, stating, "You need a reason to get excited about going on and doing it again.
