This is the classic 2011 version directed by Tomas Alfredson, with an all star British cast including John Hurt, Colin Firth, Benedict Cumberbatch, Gary Oldman to name but a few. Kathy Burke makes a heavyweight appearance as Connie. Set in the Cold War, it captures the zeitgeist perfectly. It looks set to be an award winner, big time. John le Carré is an absolute master of the genre.
