The Imitation Game movie trailer

Scenes in the hotly anticipated biopic of Alan Turing, The Imitation Game, in cinemas from 14 November and starring Benedict Cumberbatch and Keira Knightley, were filmed at Bletchley Park.

The trailer gives an early taste of the dramatic portrayal of the mathematician and Codebreaker’s life and work.

The film will receive its European premiere on Wednesday 8 October at the Odeon Leicester Square with a live cinecast from the red carpet and simultaneous screenings taking place at cinemas across the UK, as part of the 58th BFI London Film Festival. Stars Benedict Cumberbatch and Keira Knightley, and director Morten Tyldum are expected to attend the London event.

The pioneer of modern-day computing, Turing is credited with cracking the German Enigma code and the film is a nail-biting race against time by Turing and his brilliant team at Britain's top-secret Codebreaking centre, Bletchley Park, during the darkest days of World War Two. Turing, whose contributions and genius significantly helped to shorten the war, saving thousands of lives, was the eventual victim of an unenlightened British establishment, but his work and legacy live on.
