LOS ANGELES, Calif. -- IMAX Corporation and Warner Bros. Pictures announced that “300,” directed by Zack Snyder (“Dawn of the Dead”), and based on the epic graphic novel by Frank Miller (“Sin City”), will be simultaneously released domestically to both IMAX and conventional theatres on March 9, 2007.

"300" is a ferocious retelling of the ancient battle of Thermopylae, in which King Leonidas (Gerard Bulter) and 300 Spartans fought to death against Xerxes and his massive Persian army. Facing insurmountable odds, their valor and sacrifice inspire all of Greece to unite against their Persian enemy, drawing a line in the sand for democracy.

The film brings Miller's acclaimed graphic novel to life by combining live action with virtual backgrounds that capture his vision of this ancient historic tale.

The film stars Butler (“Phantom of the Opera”), Lena Headey (“The Brothers Grimm”), David Wenham (“The Lord of the Rings” trilogy), and Dominic West (“The Forgotten”).
