All the President's Men (1976)

The movie tells the story of the investigation carried out by two journalists from The Washington Post, Bob Woodward and Carl Bernstein, who manage to uncover the Watergate scandal. This 1976 classic features extraordinary performances by Robert Redford and Dustin Hoffman, as well as masterful direction by Alan J. Pakula that brilliantly evokes a very realistic and palpable atmosphere of tension. If you like political dramas, don't miss this one, perhaps the most paradigmatic in the history of cinema.
