All the King's Men (2006)

In the 1950s, in Louisiana, the smart populist, manipulative and wolf hick Willie Stark (Sean Penn) is elected Governor with the support of the lower social classes. He joins a team composed of his bodyguard and friend Sugar Boy (Jackie Earle Haley); the journalist from an aristocratic family Jack Burden (Jude Law); the lobbyist Tiny Duffy (James Gandolfini); and his mistress Sadie Burke (Patricia Clarkson), to face the opposition of the upper classes. When the influent Judge Irwin (Sir Anthony Hopkins) supports a group of politicians in their request of impeachment, Stark assigns Jack to find some dirtiness along the life of Irwin, leading to a tragedy in the end.
