Saw is an American horror media franchise created by Australian filmmakers James Wan and Leigh Whannell, consisting of ten feature films and additional media. Nine of the films primarily revolve around the fictional serial killer John "Jigsaw" Kramer, while the ninth movie revolves around a copycat killer. John Kramer was introduced briefly in Saw and developed in more detail in Saw II and the subsequent films. Rather than killing his victims outright, he traps them in life-threatening situations that he calls "tests" or "games" to test their will to survive through physical or psychological torture, believing that if they survive, they will be "rehabilitated." Kramer was killed off in Saw III, but the films continued to focus on his posthumous influence, particularly by his apprentices, and explore his character via flashbacks.
In 2003, Wan and Whannell made a short film to help pitch a potential feature film concept, after having the original script written for several years. After numerous unsuccessful attempts to receive funding in their home country of Australia, Wan and Whannell traveled to the United States, after several producers expressed interest in the project. It was ultimately successful, and, in 2004, the first installment debuted at the Sundance Film Festival and was released theatrically that October by Lionsgate. After its immensely successful opening weekend, the first of many sequels was immediately green-lit. Five directors have worked on the series: James Wan, Darren Lynn Bousman, David Hackl, Kevin Greutert and The Spierig Brothers; while Whannell, Bousman, Patrick Melton, Marcus Dunstan, Josh Stolberg, and Peter Goldfinger have written the scripts. From 2004 to 2010, each film was released on the Friday before Halloween. Both creators remain with the franchise as executive producers.
In 2010, franchise producer Mark Burg said that the seventh film, Saw 3D, would be the final installment. Lionsgate, however, expressed interest in continuing the franchise in 2012. An eighth film, Jigsaw, was released in October 2017.
