Saw III is the third installment in the Saw 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 is is why he released the Director's cut in October 2007.

Saw II is a 2005 horror film. It is the sequel to the 2004 horror film Saw. The entire film (apart from external shots) was filmed in one building over the span of 25 days. It was released in most parts of the world on October 28, 2005, but not released in Australia until December 1, 2005. Darren Lynn Bousman took over directing duties, and also co-wrote the story's script with Leigh Whannell, the original film's co-writer.
