All the President's Men
The dark side to Mr. Smith’s optimism about one man’s ability to affect change in government is the knowledge, even in Capra’s 1939 classic, that power corrupts. No instance in U.S. politics demonstrated this reality to Americans quite like the Watergate scandal. A generation that grew up believing in positive change saw their government corrupted by the paranoia of the powerful. This landmark film, which also topped our list of greatest political films, is among other things, a celebration of Freedom of the Press.
