Burnishing the legend of Edward R. Murrow, the CBS newsman who in the 1940's and 50's established a standard of journalistic integrity his profession has scrambled to live up to ever since, "Good Night, And Good Luck." is a passionate, thoughtful essay on power, truth-telling and responsibility. Though it is a meticulously detailed reconstruction of an era, the film is concerned with more than nostalgia. It unfolds, cinema-verité style, in the fast, sometimes frantic present tense, following Murrow and his colleagues and flashes back from a famous, cautionary speech that Murrow gave at an industry convention in 1958 to one of the most notable episodes in his career - his war of words and images with Senator Joseph R. McCarthy.
