Directed by Simon Langton and coscripted by John Hopkins and Le Carré himself, this is a leisurely mystery. It offers a cannily generous central performance from Guinness, who never takes off his scarf and does his best to fade into the background while a succession of striking character players hold center screen; but slowly and by sheer presence he begins to dominate the panoramic view of European treachery, deception, and disappointment. Among the terrific supporting cast are Michel Lonsdale, Mario Adorf, Vladek Sheybal, Michael Gough, Alan Rickman (a tiny, early role as a hotel clerk), Beryl Reid, Ingrid Pitt, Bernard Hepton, Michael Elphick, Rosalie Crutchley, Michael Byrne, Bill Paterson, and Maureen Lipman. Smiley's People is more interested in character than thrills, with each cameo contributing another view of the human cost of the cold war: most of the old friends Smiley seeks out react to his reappearance by saying they never wanted to see him again, and victory is only possible because Smiley discovers that his opposite number has a weakness that makes him almost sympathetic. It was originally broadcast in six hourlong episodes, and its intelligent approach works better if you watch episode-length chunks, letting one sink in before going on. --Kim Newman
