This is a good movie about the most heinous spy in America's history, but it is only based on the true story. As is so often the case, if you really want to know about Robert Hanssen and his betrayal of this country with the Russians, you should read the book. A very important fact that was left out of the movie was that Hanssen contacted the Russians about spying for them; they did not try to recruit him. When they found out who he really was, they were flabbergasted, to put it mildly. A second important fact left out of the movie was that Hanssen did not do his spying for the Russians for financial gain. The money he received from the Russians was of very little interest to him.
