Tinker, Tailor remake

I love the choice of Let The Right One In director Tomas Alfredson for Working Title's feature-length version of the John le Carré Cold War thriller Tinker, Tailor, Soldier, Spy. The 1979 BBC adaptation which starred Alex Guiness as George Smiley was brilliant television, and the recent Radio Four series the Complete Smiley had really wetted my appetite for seeing the spymaster on the big screen. Peter Morgan has been charged with adapting the material.
