All the King's Men (2006) is an adaptation of the 1946 Pulitzer Prize winning novel All the King's Men by Robert Penn Warren. It is directed by Steven Zaillian, who is also listed in the writing credits. Although the 1949 Academy Award-winning movie All the King's Men was also based on the novel, the 2006 movie is not a remake of the earlier movie, which Zaillian had never seen.

The film is about the life of Willie Stark, played by Sean Penn, a fictional character based loosely on Louisiana governor Huey Long.

As of December 2005, extended post-production has pushed the film's wide release by Columbia Pictures to September 22, 2006. Meryl Streep was originally cast for the role of Sadie Burke; however, Variety announced that she has in fact decided to drop out (she has since been replaced by actress Patricia Clarkson).

The film was first screened to the press at the Toronto Film Festival in 2006, as reported in the September 11, 2006 edition of USA Today. Although the film "drew an overflow crowd," audiences were "not bowled over". The world premiere was held at Tulane University in New Orleans on September 16, 2006.

For a movie that has received a plethora of Oscar buzz, it has garnered mixed (and mostly negative) reviews. Richard Snickel (Time Magazine) liked the movie, arguing that "it's much more faithful to the tone of the novel" than the original.

However, A.O. Scott (NY Times) expresses disappointment with the film: "Nothing in the picture works. It is both overwrought and tedious, its complicated narrative bogging down in lyrical voiceover, long flashbacks and endless expository conversations between people speaking radically incompatible accents."

Michael Medved gave All the King's Men two stars (out of four) calling it "..depressing and disappointing..", a "..stodgy melodrama.." and a "..pointless, pretentious, plodding period-piece."
