Soon to be seen fighting the windmills of our minds, Quixote style, in Christopher Nolan’s Inception, Leonardo DiCaprio’s status as one of the most in-demand talents of his generation is bolstered by the news coming out of the ether that he is to play FBI founder J. Edgar Hoover in Clint Eastwood’s forthcoming biopic.

It’s not clear if Eastwood will be focusing in on a specific time in the FBI director’s career, but with almost four decades of what was enormous change in the social and cultural mechanics of the American machine there’s a good chance that Eastwood will take this opportunity to take in the lifetime of service of Hoover.

Dustin Lance Black’s script for Gus Van Sant’s Milk was an impressive collation of the pressures and ambitions of a single individual fighting battles on all sides and I’m looking forward to seeing what he does with the life of one of America’s most controversial folk heroes.

While Public Enemies didn’t blow the bloody doors of expectation off the movie going public there is a rich vein of history to be explored and Hoover is a great place to start.

DiCaprio has already shown his biopic mettle with The Aviator and Catch Me If You Can, for Scorsese and Spielberg respectively – adding Eastwood to that list is quite an achievement.

Deadline have the news, so let’s take a moment to thank.
