The Imitation Game, starring Benedict Cumberbatch and Keira Knightley, follows the life and work of code breaker Alan Turing during World War II.
It's a thriller which not only charts Turing's genius but also delves deeply into his personal life.
Alan Turing was prosecuted in 1952 for his homosexuality and died from cyanide poisoning two years later.
While the tale of Turing and his Bletchley Park colleagues is well known in Britain elsewhere it is less so. Its hoped the new movie will change that.
