According to longtime Saw editor and now first-time director Kevin Greutert, coming up with new and interesting ways to kill people is not as easy as one might imagine, especially when you've already come up with a gauntlet of gory deaths in not one but five previous films. "There's no point in trying to hide it," Greutert said in a roundtable interview in Los Angeles last week. "I think the films have this longevity because we've managed to rise to the task, somehow. But, it made me want to cry sometimes, sitting in a room, brainstorming and pounding my head against the wall. You can think of cool ways to kill people, but it still has to fit in with our story."

"It's very complicated, he insisted. "We want to always push the envelope to the end, in terms of insanity and mayhem, but if you go too far, it becomes campy or silly. It's a really tough balancing act." Ironically, Greutert is only the guy who has to bring those death traps to life; screenwriters Patrick Melton and Marcus Dunstan are the guys who have to actually develop and design them, making sure they're not only inventive and interesting, but that they actually reflect the personalities and storylines of the characters in each film.

Cinematical recently sat down with Dunstan and Melton to discuss Saw VI, the latest installment in the long-running horror franchise, to find out where they get those wonderful – and terrible – toys. In addition to describing their creative process, they talk about challenges of collaborating with a cast and crew filled with Saw experts, and reflect on why and how their debut on Project Greenlight didn't result in a dead end for their careers, as was the case with their predecessors.
