The infamous Watergate scandal led to quite a few movies, including many documentaries, but there are five feature films that really stand above the rest in terms of how they told the story.
'Quiz Show' is an all-around triumph of filmmaking, and by far the best film Robert Redford has ever directed, and would likely be remembered more fondly if it didn't run into the buzzsaw that was 'Forrest Gump'/'Pulp Fiction' of that same year.
The film, based on the Watergate scandal, does the impossible — it builds a compelling narrative out of mostly scenes of men in suits talking in rooms, and 45 years later it still stands as one of the best movies ever made about real journalism.
