What a fantastic movie. Three of us watched it yesterday and S1 and I just loved it. All of the acting was superb. The way the film is shot (in kind of a sepia tone - not true black and white) helped with the authenticity as did the fact that so much original footage was used. Costuming, chainsmoking and little tidbits like the Kent cigarette ad were little touches that made it so complete.
My favorite line was by Murrow and it was that "dissent is not disloyality." So many people, even today, have forgotten that.
