Mark Felt: The Man Who Brought Down the White House (2017)

Factual error: When Mark Felt and the FBI Director are in a car on the way to the Watergate hearings in 1972 or 1973, from the car window, you see the WW2 memorial, which was built in 2004.

Factual error: Mark Felt is driving by the Lincoln Memorial in the background, with the WWII Memorial in the foreground. The WWII Memorial was begun in 2001 and completed in 2004, way after the movie's timeframe. (01:26:21)

Factual error: When Mark Felts initially pulls up to the FBI building he parks in the Deputy Associate Director's parking spot. He was not named to that position until after Hoover died and the current Deputy Associate Director who had that position since 1930, Clyde Tolson, resigned.

Mark Felt: The White House is packing all its crimes in separate little boxes. Watergate, the spying, the ugliness, the rot. Each thing in a different box so that no-one can put it together, so that no-one sees it's all connected. And no-one will care, but it's all the same big thing.
Sandy Smith: And Watergate? Just the gateway.

Bob Woodward: We're lost in detail.
Mark Felt: That's their plan. They want everyone confused. Confusion is control. The truth could ruin the administration.

Mark Felt: What brings you back?
Bill Sullivan: Two words: Re. Venge.
