Saw 'Tinker Tailor Soldier Spy' on dvd last night, cracking slow burn spy thriller - different beast to the tv series - if anything moves faster and plays looser with the book, Gary Oldman is a much darker Smiley than Alec Guinness was, but both versions capture the feel of the book - the fall of Britain as a world power and a sense of empire in grotty decline perfectly. The casting is superb, Colin Firth and the Cumberbatch are both particular delights to watch.
