It is perhaps inevitable that this unsettling debut from director James Wan will be compared with Se7en. Not only do they share similarly skewed serial-killing themes, but their style, tension and sheer viciousness put them in the same genre pigeonhole. Told, unusually, from the point of view of the victims, this well-acted thriller chillingly questions how far an individual will go to stay alive. Leigh Whannell (who also wrote the screenplay) and Cary Elwes become the latest playthings of a game-obsessed psychopath, finding themselves chained to opposite walls in a crumbling, subterranean bathroom, with no recollection of how they got there. With its jerky, grainy cinematography and nerve-jangling industrial soundtrack, the film is more disturbing than terrifying. It's like an extended Nine Inch Nails rock video as imagined by Dario Argento. However just when you think you've got it sussed, the movie throws in some audacious twists, resulting in one of the most memorable climaxes in recent screen history.

Two men wake up to find themselves shackled in a grimy, abandoned bathroom. As they struggle to comprehend their predicament, they discover a disturbing tape left behind by the sadistic mastermind known as Jigsaw. With a chilling voice and cryptic instructions, Jigsaw informs them that they must partake in a gruesome game in order to secure their freedom.
