The film tells the true story of the race to crack the Nazi Enigma code during World War II, with the effort led by mathematical genius Alan Turing (Benedict Cumberbatch). Helping him in his efforts are Keira Knightley (A Dangerous Method), Mark Strong (Tinker Tailor Soldier Spy) and Matthew Goode (Stoker), all adding up to an impressive cast of British talent.
Cumberbatch recently revealed how intriguing he found Turing as a character: "Turing's like Churchill described Russia: a riddle wrapped in a mystery inside an enigma."
The script, by Graham Moore, was on Hollywood's Black List of best unproduced screenplays in 2011 and seriously impressed the actor: "The [script's] conjunction of secrets, of a man who has to keep his homosexuality a secret, and the breaking of secrets in World War II, and the strands of his life it shed light on, I thought was masterful. I really knew who he was by reading the script."
Turing was central to cracking the code and is often called the father of modern computing. However, he was persecuted for his homosexuality after the war, and was prosecuted for it in 1952. He died from cyanide poisoning a few years later, in what is generally thought to have been suicide.
The Imitation Game will open the London Film Festival on 8 October and will be released generally on 14 November.
