After helping the Allies win World War II with his cryptology skills, British mathematician Alan Turing fights a much more personal war at home in the first trailer for The Imitation Game. Benedict Cumberbatch stars as Alan Turing, whose work in cracking the German Enigma Code was essential to the Allies' winning World war II. Upon returning home, taking a job at the University of Machester, he was prosecuted by the U.K. government for homosexual acts that were viewed as illegal.

Take a look at the first footage from director Morten Tyldum's drama, co-starring Keira Knightley, Mark Strong, Charles Dance and Matthew Goode, which hits theaters on November 21.

In The Imitation Game, Benedict Cumberbatch stars as Alan Turing, the genius British mathematician, logician, cryptologist and computer scientist who led the charge to crack the German Enigma Code that helped the Allies win WWII.
