The film The Enemy Within was released in 2011 and directed by Tomas Alfredson. It stars Gary Oldman, Colin Firth, and Tom Hardy in an adaptation of a John Le Carre novel set after the Cold War in Istanbul. Working Title produced the film with a budget of £20 million, but it only grossed £12 million at the box office, falling short of expectations. Marketing was done through magazines, radio, television, and a website with codes similar to those in the film.
