This wartime thriller is set in England's top-secret Bletchley Park, where the best minds in Britain gathered to crack the German code. With a screenplay by Tom Stoppard, this literate film provides an unusually incisive portrait of a brilliant young mathematician whose romantic pasions clash—and then ultimately combine—with his passion for codebreaking. In its historically accurate depiction of the Enigma coding machine, and the extraordinary challenges of deciphering it, the film also pays homage to many unsung heroes—mathematicians, linguists, electrical engineers—whose innovations helped shorten the war, and also accelerated the development of computers.
