Those who attended Comic Con '07 were in for a treat when footage from a workprint of "Saw IV" was played for them. Judging from the footage, it appears to be the opening sequence to the new film, which follows the continuing plight of the now deceased Jigsaw Killer. Though the footage was originally only available as a CAM from Comic Con, there's now an official workprint circulating the internet of the scene.

"Saw" fans can torture themselves in anticipation by clicking HERE until the film's October 26th release date.
