Not too long ago, the fate of FOX's surprisingly scary and engaging take on William Peter Blatty's The Exorcist was up in the air. Despite earning mostly positive reviews from critics, the series had been sequestered on the network's Friday night schedule, earning ratings left its season 2 renewal a question for far longer than usual. Nevertheless, the series will continue with a mostly new cast and setting for the ongoing adventures of demonbusters Father Marcus Keane (Ben Daniels) and Father Tomas Ortega, when it returns in the fall.

As evidenced by the new Montana setting and the inclusion of Star Trek star John Cho as Andrew Kim and Deadpool's Brianna Hildebrand as troubled teen Verity Escala, The Exorcist is something of an anthology series, in that its producers see the characters of Keane and Ortega journeying to a new locale to deal with matters of demonic possession as the future of the series. Throw in the ongoing storyline that involves the Vatican and Father Bennett (Kurt Egyiawan) and you have the makings of a series with its own fascinating mythology and arc that may one day be resolved.

At this year's San Diego Comic-Con, Screen Rant participated in an interview with series creator and executive producer Jeremy Slater and co-executive producer Sean Crouch. The two touched on the changes in season 2 and how they view the series as having a six or seven season arc.

Slater: You can't tell a seven-year story about one family that just keeps getting possessed over and over again without the audience starting to hate you for putting one family through so much shit. So the idea is every year we'll have a different case, we'll have a different sort of possessed individual and different family, and but it's Marcus and Thomas -- our priests, our recurring characters -- that you're gonna follow and have that investment with.

Crouch: Six seasons and a movie, that's our aim [laughs]. And then we go into the Vatican this season and really get into that story with Father Bennett and hopefully that's our connective tissue in the mythology of the show. It could go for six or seven seasons and hopefully have a very satisfying ending.

Slater: We've sort of plotted it out very generally, just in case, so we know that we have an end point in mind for this, and we will answer every question at some point along the way. That's really important to us.

While the idea of plotting a series' endpoint is as familiar as the "six seasons and a movie" line, it can also become a source of excitement or trepidation for those watching. Still, given that Slater and Crouch managed to successfully establish an underlying sense of intrigue and a larger story in the background of the Rance family's encounter with a demonic entity, perhaps FOX's The Exorcist is deserving of some benefit of the doubt when it comes to the show's ability to defy expectations.

After all, few people thought adapting a horror movie classic into a television series (on a broadcast network no less) was a good idea. After the first season of The Exorcist it's a good bet some people have changed their minds.
