Leonardo DiCaprio stars in this sweeping biopic of J. Edgar Hoover, the first head of the FBI. Controversial in his tactics and his personal life, Hoover became a pillar of American society for over fifty years. Directed by Clint Eastwood and a supporting cast that includes Dame Judi Dench, Armie Hammer and Naomi Watts, it's a glossily-made portrait of a controversial figure who had more than his share of secrets.
