VIDEO: Behind the scenes at Bletchley Park and The Imitation Game

Wartime blockbuster The Imitation Game held its premiere at Bletchley Park on Tuesday evening, and the Citizen was there for the show.

Ben Raza’s review will appear online shortly - but videographer Natalee Hazelwood visited hours earlier to see the historical site for herself.

From next week Bletchley Park will be running a major new exhibition, taking visitors behind the scenes of the highly anticipated movie.

Entering the exhibition on a red carpet in the Billiard Room, visitors will first see costumes worn by the stars, Benedict Cumberbatch and Keira Knightley as Alan Turing and Joan Clarke, as well as the boys at Sherborne School, where a young Alan was played by Alex Lawther

Once inside the Ballroom itself, fans can pose for a photo in the very bar seen in the film, and discover more behind-the-scenes gems.

Items on display will include the Enigma intercepts Alan Turing stuffs into his socks and trousers to sneak them off-site, the scribbles made by John Cairncross (played by Downton Abbey’s Allen Leech), and the prototype Bombe machine Turing names Christopher, after his first love and created especially for the film.

Bletchley Park was home to Britain’s code-breaking triumphs during the Second World War, including breaking the “insoluble” Nazi Enigma codes and beating Japanese cryptology.

First created in 1938, the team’s work was so secret that everyone who worked there signed the Official Secrets Act for life, meaning that the public only started to learn about its achievements decades later.

Alan Turing, who is played by Benedict Cumberbatch in The Imitation Game, was one of around 10,000 people working at Bletchley Park, and their work is generally reckoned to have shorted the war by two or three years.
