From NetFlix:

Leonardo DiCaprio stars in this riveting biopic as J. Edgar Hoover, the longtime FBI director as notorious for his overzealous methods of law enforcement as for the rumors regarding his cross-dressing and close relationship with protégé Clyde Tolson.

Looking for an “Actor’s actor” ? Go no farther. Current movie reviews lament the fact that we are seeing a series of young male wannabes with tight abs who don’t last because they lack the acting skills. But Leonardo DiCaprio is the quintessential chameleon. His portrayal of J. Edgar is nothing less than astonishing. Even if it were complete fiction, the film would be riveting (as the NetFlix caption says).

For a discussion of historical accuracy you can read the Wikipedia article. This article also discusses Hoover’s sexuality. Clint Eastwood, the director, wisely stayed away from any depiction of cross-dressing (except for one brief suggestion) or explicit sexual behavior (except for some kisses). Just enjoy the marvelous production and stop wondering how much is true. If even a little bit were true, Hoover was a dangerous paranoid.

This is NOT a film for titillation. Instead it focuses on Hoover’s bulldog no-holds-barred approach to getting his way, even if it meant blackmailing every politician in Washington. It focuses also on: Hoover’s insecurity, his emotional dependence on his mother (with whom he lived all his life) and Clyde Tolson (who had his own house), his lying, and his barely legal methods.

In all fairness you should read the Wikepedia biography of Clyde Tolson. He was NOT the seemingly weak character portrayed in the film.

Nixon is portrayed as a profane thug.

Additionally I marvel at the long list of known supporting actors, among whom we find:

• Armie Hammer (who?) played Clyde Tolson very well. Believe it or not, Armie Hammer’s father is the CEO of the Armand Hammer Foundation. Armie was 25 years old during the filming.
• Josh Lucas played Charles Lindberg, who was very important to the story.
• Damon Herriman (who?) played Bruno Hauptman, the supposed kidnapper of the Lindberg child. Today the debate still rages over the guilt of Haputman. Once again see the Wikipedia article.
• Naomi Watts played Helen Gandy, the famous personal secretary for Hoover for 54 years. She is most remembered for spending weeks after Hoover’s death destroying Hoover’s blackmail materials, his “Personal File” (much to Nixon’s chagrin). Once again see Wikepedia.
• Big surprise: I kept staring at Hoover’s mother and couldn’t believe my eyes. Indeed it was Judi Dench. She spoke a perfect American accent. More to the point she was a professional support actor who received no special credit.
• Remember Dermot Mulroney (My Best Friend’s Wedding)? He played Colonel Schwarkopf.
• My own award for “Appearing everywhere but not famous” goes to Zach Grenier (who?) whom I once met in person in the San Franciscon Museum of Modern Art. His is the only name I can drop because I never meet anyone famous. Look him up in IMDB and I am willing to bet you have seen him somewhere. He is currently playing a pain in the neck in “The Good Wife” on TV.

Officially I go out on a limb: DO NOT MISS THIS FILM!
