J. Edgar stars Leonardo DiCaprio (Titanic) as J. Edgar Hoover, the former director of the FBI. An aging Hoover dictates his memoirs to a writer, focusing on his rise to power and the policies and procedures that he implemented during his reign. Told through flashbacks, the story takes place over the course of about 50 years but mainly concentrates on the Lindberg baby kidnapping case, as well as on Hoover’s relationship with his secretary, Helen Gandy (The Ring’s Naomi Watts), and his associate director Clyde Tolson (Armie Hammer, the twins from The Social Network).
