Enigma is a 2001 British film about the Enigma codebreakers of Bletchley Park in World War II. The film, directed by Michael Apted, stars Dougray Scott and Kate Winslet. The film's screenplay was by Tom Stoppard and is based on the novel Enigma by Robert Harris. Set in 1943 amidst the largest convoy deployment from the US to Britain, cryptanalyst Tom Jericho returns to Bletchley Park to help find the code to the U-Boats' Enigma communications. On finding a cypher containing highly classified information, hidden by a former lover who has gone missing, he attempts to solve the code while working on cracking the German U- Boat code against a background of subterfuge, spies and the Katyn massacre. The film was co-produced by Mick Jagger, who provided funding for the film, as well as access to his own Enigma machine. It was shot in England, Scotland and the Netherlands. Critical reviews were largely positive, although there was criticism of the largely fictional storyline which does not mention the real codebreaker Alan Turing.
