Saw is a 2004 American horror film directed by James Wan. It is Wan's feature film directorial debut. The screenplay, written by Leigh Whannell, is based on a story by Wan and Whannell. The film stars Cary Elwes, Danny Glover, Monica Potter, Michael Emerson, Ken Leung, Tobin Bell and Leigh Whannell. In the film, Elwes and Whannell portray two men who awake to find themselves chained in a large dilapidated bathroom, with one being ordered to kill the other or his family will die. It is the first installment in the Saw franchise.
The debut of Wan and Whannell, the screenplay was written in 2001, but after failed attempts to get the script produced in Wan and Whannell's home country of Australia, they were urged to travel to Los Angeles. In order to help attract producers they shot a low-budget short film of the same name from a scene out of the script. This proved successful in 2003 as producers from Evolution Entertainment were immediately attached and also formed a horror genre production label Twisted Pictures. The film was given a small budget and shot for 18 days.
Saw was first screened on January 19, 2004. Lionsgate picked up the rights and released the film in the United States and Canada on October 29, 2004. Critical responses were generally mixed and divided, but the film gained a cult following. Compared to its low budget, Saw performed very well at the box office, grossing more than $100 million worldwide and becoming, at the time, one of the most profitable horror films since 1996's Scream.
