In one corner, you had Richard Nixon, the Oval Office inhabitant who whose minions acted surreptitiously, and illegally, to further his presidential campaign chances. In the other corner, you had Mark Felt, a high-ranking FBI agent who helps guide the Washington Post coverage of the Watergate affair by becoming the informant quickly nicknamed Deep Throat. Felt was identified only by his alias when portrayed so brilliantly by Hal Holbrook in the 1976 movie All the President’s Men, which told the Watergate story mostly through the eyes of reporters Bob Woodward and Carl Bernstein, played by Robert Redford and Dustin Hoffman. Here, Felt gets top billing, and is played by Liam Neeson, in this 2017 movie about a 45-year-old case of presidential abuse of office and a career FBI agent determined to see justice done. But why watch this movie now: What possible relevancy could Mark Felt have today?
