Saw III is the third installment in the Saw horror film series. The film is a joint effort of both Saw's writers/directors, James Wan and Leigh Whannell, and Saw II's writer/director, Darren Lynn Bousman.
The film focuses on the again resurfaced Jigsaw Killer, the antagonist of the previous films, who is working with his unstable apprentice Amanda to finish the final tests he had prepared and planned before he dies. The film also contains additional backstory information on the two antagonists.
The film has been dedicated to Gregg Hoffman, producer of the first two movies. Hoffman died on December 4, 2005, shortly after the official Lions Gate Entertainment announcement of Saw III.
According to producer Daniel J. Heffner, the film was toned down 7 times to obtain the "R" rating. The Unrated DVD, released on January 23, 2007, features a 113-minute cut of the film that includes more gore. On the commentary track, Bousman notes that this is not his original, two-hour-plus cut of the film, and that it may see release on DVD in the future.
According to director Darren Lynn Bousman, the MPAA ratings board was less concerned with the film's graphic violence because television shows like CSI have expanded the scope of what is acceptable viewing with their graphic depictions of crime scenes and autopsies. Bousman says the MPAA is more concerned with emotional torture that disturbs the audience.
Almost all the transitions from one place to another (such as from Kerry's trap to Chris' place, and Jigsaw's lair to Jeff's crate) were not made using digital effects. The transitions were shot on the spot. So when the camera moves from Troy's crime scene to Kerry being in the bathtub, Dina Meyer had to run, take off all her clothes, and jump into the tub. If you look closely, you can still see the water moving from when she got in.
According to Leigh Whannell, Adam had a lot more scenes in the original film. One of which was the scene between Adam and Amanda, included on the Saw III DVD bonus features.Wikipedia
