Benedict Cumberbatch and Keira Knightley star in The Imitation Game, a movie about British cryptologists' top-secret efforts to break the German Enigma cipher and defeat the Nazis during World War II.

Cumberbatch will be playing pioneering computer scientist Alan Turing, while Keira Knightley will play Joan Clarke, a member of his team.

Turing is best known for the Turing Test for artificial intelligence, as well as for his mistreatment at the hands of authorities who attempted to "cure" his homosexuality. He worked on the Bombe machines that supposedly broke the German Enigma encryption code, which allowed the Allied forces to decipher intercepted military communications.

Because of that, they won several key battles and broke the German sihpping blockade,
