Jigsaw and his apprentice Amanda are dead.

Now, upon the news of Detective Kerry's murder, two seasoned FBI profilers, Agent Strahm and Agent Perez, arrive in the terrified community to assist the veteran Detective Hoffman in sifting through Jigsaw's latest grizzly remains and piecing together the puzzle.

However, when SWAT Commander Rigg is abducted and thrust into a game, the last officer untouched by Jigsaw has but ninety minutes to overcome a series of demented traps and save an old friend or face the deadly consequences.

We caught up with 'Saw' director Darren Bousman whilst he was speaking at a press conference at the lofty Metropolitan Hotel in Toronto. "I'm excited and honored to be part of such an amazing franchise that keeps on ticking," enthuses director Darren Bousman who, to date, has delivered three 'Saw' sequels including the upcoming 'Saw IV.'

What was you primary concern going info the making of this fourth movie? "Our job was to figure out how to make the story move forward having killed Jigsaw yet not want to make a movie without Tobin Bell."

Why keep doing them after it looked like the third was the end of the line?! "Yeah," he laughs, "We keep doing them because we keep coming up with fresh ideas!" adding a huge gut laugh for theatrics.

"In 'Saw III' I thought it was my final one and I said, 'Kill everybody, kill 'em all!' and I went in and I killed Tobin" he again laughs, well aware that he painted himself into a corner. "Now I'm like back, everyone's dead, what am I going to do? I was not only thinking about the future but we were thinking about the past as well. I think that was the hardest thing about doing 'Saw IV.' We had to think ahead ... since the franchise is being turned over to David Hackl for 'Saw V'," he announces. "We had to go somewhere with it. We had to think about these characters we were introducing. Where will they be, where will they go to?"

Where do the ideas for all the specific actors and their traps come from? "Actually, when we do the stories we'll insert a trap later," he explains. "In the conception of the movie we basically say, 'People will get into a trap,' and we'll go with the logic and the flow the story. The traps don't drive the story, the story drives itself and then people get into situations."

"The traps become easier and easier," Bousman continues. "David Hackl, he's the production designer of these traps. He can take a simple microphone and turn it into a trap. But I think the 'Saw' films have become known for their twist and the 'Did we get you?' And this entire film is a lead up to a 'Did we get you?' That was the hardest thing this year. The whole movie was conceived with writers Marcus Dunstan and Patrick Melton around the last twenty minutes and we had to backtrack to the very first frame."

How easy or hard was it to keep things straight on set with all these deaths and traps, etc.? "Yeah, there are storylines running concurrently with flashback after flashback. It's a lot to take in. But, we tried to make it vrry clear what needed to happen, what had happened, what was going to happen and maybe what was going to happen in future scripts, part five. So that was crucial information to have, otherwise you couldn't play the scene."

What do you say to those that say these 'Saw' films only work because of violence often applauded for rendering flesh from bone?! "We always get bashed for gore for the sake of gore," Bousman defends. "It's easy to look at that on the surface and see red stuff all over the place. But if you go beneath the surface these aren't movies we make for the critics. This isn't some critic darling - a one million dollar movie we hope to win an Academy Award for a moral message. At the same time this has a bigger moral message than a lot of films that do win.""I watch horror films all day long and most of them are just blood and violence. You got hot teenagers, you get 'em naked with sex and do some killing. That's not what the 'Saw' films are, I challenge people to look beneath the surface, take away the scenes of blood and there's a movie. You take away the blood of most horror movies and you've got nothing left."
