Mark Felt: The Man Who Brought Down the White House is a top class production made in 2017. It is a pleasure for me to watch such a good movie. If a movie can keep me focused for the full movie time, that's really great. The film is interesting, it does not get boring, it does not get long and although it is not an original production, good acting and skilfully written script make it worth watching. I've been a big fan of such cinema for some time. You can watch the movie online here or download it.
