Filming is now under way in London on Tomas Alfredson's Tinker, Tailor, Soldier, Spy for Working Title and StudioCanal. The Swedish director's last film was the stunning, critically acclaimed horror Let the Right One In. Alfredson is expected to bring the same deep coldness that imbued his snowy vampire tale, to this story of Cold War espionage. Producer Tim Bevan said of the director "Tomas is one of the most gifted directors in the industry and we are really looking forward to working with him on such an exciting project."

Set in 1970s London, Tinker, Tailor, Soldier, Spy is the eagerly awaited feature film adaptation of John le Carre's bestselling novel which sees recently retired MI6 agent George Smiley doing his best to adjust to a life outside the secret service.  However, when a disgraced agent reappears with information concerning a mole at the heart of the Service, Smiley is drawn back into the murky field of espionage. He finds that past histories, rivalries and friendships make it far from easy to pinpoint the man who is slowly destroying the British establishment.

With a screenplay from Peter Straughan (The Men Who Stare at Goats) and Bridget O'Connor the film boasts a stand-out cast. Gary Oldman stars as George Smiley, a part famously occupied by Alec Guinness in the 1979 BBC adaptation, and he is joined by Oscar-nominated Colin Firth (The King's Speech), Tom Hardy (Inception), Benedict Cumberbatch (Atonement, Four Lions), David Dencik (The Girl with the Dragon Tattoo), and Mark Strong (Sherlock Holmes). The production is shooting all over the capital for the next three weeks at locations which include Aldwych, Kensington Gore, Hampstead, Chiswick, Maida Vale and East London.

Tinker, Tailor, Soldier, Spy reunites Alfredson with director of photography, Hoyte van Hoytema, and editor, Dino Jonsäter, who both worked with him on Let the Right One In. Other members of the creative team include the production designer Maria Djurkovic, costume designer Jacqueline Durran, and hair and make-up designer Felicity Bowring.
