starchEnigma is a 2001 Anglo-American 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 World War II. This was the final film to be scored by John Barry.
In 1943 amid the largest convoy deployment from the US to Britain, cryptanalyst Tom Jericho (Dougray Scott) returns to Bletchley Park to help the codebreaking team reacquire their ability to read U-Boats' Enigma communications. Obsessed with his missing former girlfriend Claire (Saffron Burrows), he and Claire's roommate Hester (Kate Winslet), also employed at Bletchley, work on unraveling the mystery of Claire's disappearance. Although the story is highly fictionalised, 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.
