J. Edgar Hoover, played by Leonardo DiCaprio, is a single-minded individual fixated on eradicating Communists, anarchists and other revolutionaries taking action against the U.S. government. Early in his career, Hoover, builds the agency’s reputation, becoming the sole arbiter of who is hired and fired.
One of his employees, Clyde Tolson, quickly becomes Assistant Director and remains be Hoover’s confidant and companion for the rest of his life. Though Hoover’s memories have him playing a greater role in the many high profile cases the FBI was involved in (the Lindbergh baby kidnapping, the arrest of bank robbers like John Dillinger), they also show his aptitude at manipulating politicians he is forced to work with throughout his career.
With some decent acting and directing, though somewhat slow at times, J. Edgar offers a unique perspective into the life of a man who dedicated himself entirely to his country.
