All the King's Men is a 2006 film adaptation of the 1946 Pulitzer Prize-winning novel All the King's Men by Robert Penn Warren. It was directed by Steven Zaillian, who also produced and scripted.

The story is about the life of Willie Stark (played by Sean Penn), a fictional character resembling Louisiana governor Huey Long. The film co-stars Jude Law, Kate Winslet, Anthony Hopkins, James Gandolfini, Mark Ruffalo, Patricia Clarkson and Jackie Earle Haley in his first film since Maniac Cop III: Badge of Silence thirteen years prior.

All the King's Men had previously been adapted by Robert Rossen in 1949. Although it does not follow the 1949 film's narrative and is more faithful to the novel than the earlier movie, the 2006 film is often considered a remake of the 1949 version. According to IMDb, Zaillian never saw the original film, and adapted the screenplay solely from Warren's novel.

Filming took place in New Orleans, Morgan City, Donaldsonville, at the Louisiana State Capitol in Baton Rouge and many other places in Louisiana.

The world premiere was held at the Toronto Film Festival on September 11, 2006. There the film was first screened to the press. A special screening was held at the Tulane University in New Orleans on September 16, 2006.
