The trailer to J. Edgar was released last night, and it finally gives viewers a sense of what the highly anticipated Clint Eastwood-directed biopic is all about. Leonardo DiCaprio plays J. Edgar Hoover, the director and face of the FBI for nearly 50 years. Hoover shaped modern crime-fighting and investigation, but his personal life might be the most fascinating thing about him. Judging by the trailer, the notoriously prickly and paranoid Hoover would’ve hated this movie--and not just because DiCaprio wears a pudgy latex old-man mask for many of the scenes. HD Trailer after the jump.

The film looks to tackle J. Edgar Hoover’s alleged homosexual relationship with his deputy, Clyde Tolson (Armie Hammer). According to Salon, Hoover and Tolson were “Inseparable for 44 years…[and] the two top G-men vacationed together, often dressed similarly and continue their cohabitation even after death. They're buried alongside one another.” Hoover is also said to have “hunted down and threatened anyone who dared to utter an innuendo about his sexual preference.”

The clip from the trailer of DiCaprio putting his hand on Armie Hammer’s in the back of a car would have been enough to earn the two life-long surveillance from the FBI were J. Edgar Hoover still alive. He’s not though, and it will be interesting to see how the biopic depicts such a famously secretive man.

Our favorite story about Hoover comes from an out-of-print book titled No Left Turns. The author, a former FBI agent, says that J. Edgar had specifically instructed his motorcade to never take left turns. No matter how long the journey, they had to only perform right turns, circling blocks repeatedly until they got to their destination.

Here are some other things we learned from the trailer about J. Edgar Hoover:

He was a momma’s boy; He was really into keeping files on people, especially Eleanor Roosevelt and John F. Kennedy; He once received a kiss on the cheek from Shirley Temple (or a Shirley Temple look-a-like).
