Saw is a 2004 American horror film directed by James Wan in his feature directorial debut, and written by Leigh Whannell, from a story by Wan and Whannell. It stars Whannell alongside Cary Elwes, Danny Glover, Monica Potter, Michael Emerson, and Ken Leung. The film tells a nonlinear narrative revolving around the mystery of the Jigsaw Killer, who tests his victims' will to live by putting them through deadly "games" where they must inflict great physical pain upon themselves to survive.
