Trivia

The voice heard on the phone call to Howard Hunt from reporter Bob Woodward is actually Robert Redford's voice taken from All the President's Men, where he portrayed Woodward.

Woody Harrelson plays E. Howard Hunt in this series. There is a very unusual commonality between the Hunt and Harrelson families. For much of his later life, Hunt was a figure of speculation in the shadowy world of John F. Kennedy assassination conspiracy theories, and after his 2007 death two of his sons claimed that Hunt made a "deathbed confession" of his involvement in Kennedy's murder (though Hunt's widow and other children believed that the sons took advantage of a weakened and ill Hunt to coach him through the "confession" they wanted). Woodrow Tracy "Woody" Harrelson is a son of Charles Voyde Harrelson, a convicted hitman for organized crime and drug trafficking figures. Charles Harrleson once claimed that he was Kennedy's true assassin, though throughout his life he vacillated between implying this was true and admitting that it was a ploy to try to reduce his sentence for the murder of a federal judge. Charles Harrelson died in prison (also in 2007).

In the end credits, Woody Harrelson and Justin Theroux get "diagonal billing", where Harrelson's name is first when read top down, but Theroux's name is first when read left-to-right. This was invented for Paul Newman and Steve McQueen's credits in The Towering Inferno (1974), released in 1974, the year of the conclusion of the Watergate scandal and of President Nixon's resignation.

F. Murray Abraham plays Judge John Sirica. In All the President's Men (1976) (about the Washington Post investigation into the Watergate break-in) he appeared as 'Arresting officer #1'.

Part of the series was filmed in Poughkeepsie, NY where G. Gordon Liddy had been the Dutchess County prosecutor and where his wife, Frances, was from.
