I saw this movie on Saturday night, and let me tell you, it is a great movie.
The movie covers about four weeks in 1954 at the climax of Senator Joseph McCarthy's anti-communist witch-hunts. Edward R. Murrow and the CBS newsroom courageously challenged McCarthy's fear-mongering anti-Americanism, knowing that they too would inevitably be labeled as communists by McCarthy.
At several points in the film, I wanted to cheer. I highly recommend this movie.
