"Good Night, and Good Luck" is an excellent movie--as a piece of cinema, as a piece of journalism, and as a political intervention. The use of Eisenhower on the blessings of the writ of habeas corpus is especially nice. Go see it.
It is, of course, about Tail-Gunner Joe McCarthy, Edward R. Murrow, Fred Friendly, and Bill Paley. It is also about Richard Cheney, George W. Bush, and their circular firing squad of flying attack monkeys.
