I've just watched the new video of "Tinker, Tailor, Soldier, Spy". I can remember watching the first version years ago as it played on PBS after coming over from the BBC. In that one, Alec Guinness was remarkable playing the very understated George Smiley. In the new one, Gary Oldman is equally remarkable playing that part. The movie is a superb telling of a period during the Cold War when word came that there was a Russian mole high in the British Secret Service and the struggle to locate and identify that mole. If he really existed. If you can take the slow pace of a thinking man's spy thriller, this is a great movie which I highly recommend.
