Exam is a 2009 British psychological thriller film written by Simon Garrity and Stuart Hazeldine, directed by Stuart Hazeldine and starring Colin Salmon, Chris Carey, Jimi Mistry, Luke Mably, Gemma Chan, Chuk Iwuji, John Lloyd Fillingham, Pollyanna McIntosh, Adar Beck and Nathalie Cox. The film is set in present-time United Kingdom in an alternate history. Eight candidates dress for what appears to be an employment assessment exam. They enter a room and sit down at individual desks. Each desk contains a paper with the word "candidate", followed by a number, from one to eight. The Invigilator, a representative of the company named DATAPREV, explains that the exam takes 80 minutes and consists of one question only, and that there are three rules: they must not talk to the Invigilator or the armed guard at the door, spoil their paper, or leave the room. Not obeying the rules will result in disqualification.
