One scene in the movie that never happened in real life is the scene where Bernstein lures Dardis’ receptionist away with a fake phone call in order to speak to Dardis. It is said that this scene is not found in Woodward and Bernstein’s book. http://mentalfloss.com/article/78307/13-investigative-facts-about-all-presidents-men,. - Courtlyn Plunkett

The movie used the actual names of the Watergate burglars along with Carl Bernstein and Bob Woodward's real names of investigative journalists who wrote about Watergate. –Caroline Collier

The scene where Bob Woodward made a phone call to Kenneth Dahlberg where Dahlberg ends the conversation saying that his neighbor's wife had been kidnapped recently had really happened. It occurred on July 27, 1972, in Minnesota a few days before Bob Woodward called Dahlberg. -Kyle Moore

The film accurately portrays Woodward’s meetings with “Deep Throat” by showing the secret meetings in a parking garage as well as placing a flag in a flower pot to signal meetings. – Courtlyn Plunkett

As the Watergate scandal happened four years prior to the release of the movie, the movie is entirely focused on the investigation part of the Watergate Scandal and never shows the results other than the headlines it created. As audiences lived through the consequences of the investigation themselves, focusing on the process of the investigation was probably more important to audiences. -Kyle Moore

The movie came out only four years after Watergate and displayed the story of Watergate very accurately. In fact, the Library of Congress selected the movie for preservation for being ‘culturally, historically, and aesthetically significant.’ The editor of the Washington Post was devoted to ensuring that the film portrayed the story accurately because he wanted to show that newspapers were ethical and honest institutions that were out to find the truth.-Lake Wiley https://en.wikipedia.org/wiki/All_the_President%27s_Men_(film)
