Saw is a 2004 psychological horror film directed by James Wan. The film introduces audiences to the notorious Jigsaw Killer, a villain who concocts deadly, intricate games for his victims as a warped form of moral retribution. The movie marks the directorial debut of James Wan and was co-written by Leigh Whannell. It stars Whannell, Cary Elwes, Danny Glover, Ken Leung, Michael Emerson, Tobin Bell, and Monica Potter.
The narrative primarily unfolds through the plight of two men, Dr. Lawrence Gordon (Cary Elwes) and Adam (Leigh Whannell), who wake up chained in a decrepit bathroom, with no memory of how they got there. A dead body lies in the same room, holding a revolver and a cassette player. As Dr. Gordon and Adam listen to the tapes found in their pockets, they realize they're trapped in one of Jigsaw's sadistic games.
The film cleverly interweaves flashbacks and detectives' efforts to track down Jigsaw, gradually revealing the intricate, disturbing logic behind Jigsaw's games. Saw is renowned for its twist ending, suspenseful plot, and its exploration of the lengths that people will go to survive, making it a standout film in the horror genre. Produced on a modest budget of $1.2 million, Saw earned over $100 million globally, making it one of the most profitable horror films ever. It has been followed by nine sequels.
