Leonardo DiCaprio Stars As J Edgar Hoover In New Biopic - Will He Finally Get His Oscar?

With Clint Eastwood at the helm, Naomi Watts and Judi Dench in supporting cast roles, it's evident the biopic drama telling the story of J Edgar Hoover is going to be a big-budget, high-quality offering.

Throw in the mix one Leonardo DiCaprio at the helm, playing the complex leader of the FBI through some of the most tumultuous events in US history, and this becomes one of next year's early must-sees (out January 2012, just in time for... Oscar nominations, who'd have thought?)

Until then, there's the trailer above and the official blurb below:

During his lifetime, J. Edgar Hoover would rise to be the most powerful man in America. As head of the Federal Bureau of Investigation for nearly 50 years, he would stop at nothing to protect his country. Through eight presidents and three wars, Hoover waged battle against threats both real and perceived, often bending the rules to keep his countrymen safe. His methods were at once ruthless and heroic, with the admiration of the world his most coveted, if ever elusive, prize.

Hoover was a man who placed great value on secrets—particularly those of others—and was not afraid to use that information to exert authority over the leading figures in the nation. Understanding that knowledge is power and fear poses opportunity, he used both to gain unprecedented influence and to build a reputation that was both formidable and untouchable.

He was as guarded in his private life as he was in his public one, allowing only a small and protective inner circle into his confidence. His closest colleague, Clyde Tolson, was also his constant companion. His secretary, Helen Gandy, who was perhaps most privy to Hoover’s designs, remained loyal to the end…and beyond. Only Hoover’s mother, who served as his inspiration and his conscience, would leave him, her passing truly crushing to the son who forever sought her love and approval.

As seen through the eyes of Hoover himself, “J. Edgar” explores the personal and public life and relationships of a man who could distort the truth as easily as he upheld it during a life devoted to his own idea of justice, often swayed by the darker side of power.
