The second series of the highly successful drama “The Bletchley Circle” started airing on ITV on 6 January 2014 which means I can start to reveal the embargoed behind-the-scence reportage I was lucky enough to be able to capture for Bletchley Park when they were outdoor filming there in June 2013. It was only a few years ago that the WWII work and legacy of Bletchley Park was still a closely guarded secret. It is now pretty much well known across the world as the “home of the Codebreakers” and the cradle of modern computing. It has also been woven into mainstream drama and film as a rich source of stories but a major drawback of the film “Enigma” was that none of the Bletchley Park scenes were shot on location. No so with the latest Hollywood film “The Imitation Game” starring Benedict Cumberbatch and Keira Knightly (not allowed to shoot this one – boo) or the ITV drama The Bletchley Circle which was critically acclaimed in 2012 (which I was – hooray!).
