Other mistake: The chronology of dates on the teletype printer at the end of the film are not in the correct order. We see "March 13, 1975" followed by "January 3, 1975", which is then followed by two August 1974 dates.
All the President's Men (1976)
1 other mistake - chronological order
Directed by: Alan J. Pakula
Starring: Robert Redford, Dustin Hoffman, Martin Balsam, Jack Warden
Visible crew/equipment: When Bernstein rushes into the phone booth early in the movie, in the metal edge of the booth you can see a reflection of the camera man.
Bob Woodward: Well, who is Charles Colson?
Harry Rosenfeld: The most powerful man in the United States is President Nixon. You've heard of him? Charles Colson is special counsel to the President. There's a cartoon on his wall. The caption reads, "When you've got 'em by the balls, their hearts and minds will follow."
Trivia: According to an interview with Robert Redford, filming was attempted in the actual Washington Post newsroom, but turned out to be impossible because many too many employees were aware of the camera, and some even tried to act. In fact, some employees would disappear and apply make up. They eventually had top spend almost $500,000 to recreate the newsroom on the studio lot.
