***I read the novel by John le Carré many years ago. I read most his novels, and found them boring - no action.***
Years ago, 1966 to be exact, I saw THE SPY WHO CAME IN FROM THE COLD, a top notch movie made to show that spy work is not all James Bond. It is the only time I ever fell asleep while trying to watch it in the movie theater. Bo-ring.
Probably why it's never on T.V. Another successful Le Carre' snoozefest.
That movie is a classic. It's probably Richard Burton's best performance. The rest of the cast, Claire Bloom, Oscar Werner, Peter Van Eyck; are all great as well. It really has several twists that make it difficult to figure out until the end.
The only problem with Le Carre is that he is one of those lefties who felt that all sides in the cold war were essentially the same.
