Enigma is a 2001 espionage thriller film directed by Michael Apted from a screenplay by Tom Stoppard. The script was adapted from the novel Enigma by Robert Harris, about the Enigma codebreakers of Bletchley Park in the Second World War. Although the story is highly fictionalized, the process of encrypting German messages during World War II and decrypting them with the Enigma is discussed in detail, and the historical event of the Katyn massacre is highlighted.
The story, loosely based on actual events, takes place in March 1943, when the Second World War was at its height. The cryptanalysts at Bletchley Park, Buckinghamshire, have a problem: the Nazi U-boats have changed one of their code reference books used for Enigma machine ciphers, leading to a blackout in the flow of vital naval signals intelligence. The British cryptanalysts have cracked the “Shark” cipher once before, and they need to do it again in order to keep track of U-boat locations. © Manhattan Pictures International, LLC.
