In the movie, Murrow, played by David Strathairn, decides to expose the tactics of McCarthy by using senator's own words. Murrow's boss, William Paley, the legendary head of CBS, is by turn supportive and plenty worried about the impact the report will have on his network. But Paley would relent and the program aired, intensifying a public outcry against McCarthy. In late 1954, the senator was censured by his colleagues in the U.S. Senate.
There is inevitably a political side to a film that looks at a period of history in which many Americans then and now believe civil liberties were threatened in the hunt for communists.
