It’s been six years since Kevin Greutert’s Saw 3D: The Final Chapter hit theaters. It was supposed to conclude the franchise that was first spawned in 2004 with James Wan’s indie SAW.

The film ended with a huge reveal: Dr. Gordon (Cary Elwes) was behind a cult of Jigsaw followers that appeared to be on a global level. While obviously closing the door on the franchise, it weirdly left many questions unanswered. There’s a reason, which is revealed by screenwriters Patrick Melton and Marcus Dunstan, the duo behind the upcoming The Neighbor (Sep. 6).

“It was our original intention to make the final ‘Saw’ film in two parts,” they explained to Bloody Disgusting. “But when ‘VI’ didn’t do so well, the studio [Lionsgate] got nervous and we were only allowed to make one more. “The big reveal of Dr. Gordon was a bit underserved as a result,” they added, “perhaps creating more questions than answers. There were several ideas we never quite figured out. But I don’t want to say what they were, because you never know what might happen in the future.” They continue: “I’m excited and curious as everyone else for the next one coming next year. It’ll be cool to get a hard R horror film that isn’t supernatural (although ‘Don’t Breathe’ looks pretty darn fantastic). There are great people involved, including the brothers behind the camera. Hopefully we’ll at least be invited to the premiere.

The next SAW film, in theaters October 27, 2017, is to be directed by Michael and Peter Spierig.

Josh Stolberg and Pete Goldfinger – the same scriptwriting duo behind Piranha 3D, Piranha 3DD, and Sorority Row – were previously reported as the film’s writers.
