I just saw the trailer for 300, an adaptation of the comic-novel by Frank Miller. See trailer here or at the official site. It looks really interesting. The directing seems a combination of Rome (HBO) and Sin City (in color). 300 is out in 2007. For now, there’s a cool production blog for the film. See here.

The premise (provided by allmovie.com):
Sin City author Frank Miller’s sweeping take on the historic Battle of Thermopylae comes to the screen courtesy of Dawn of the Dead director Zack Snyder in this CG-heavy adventure starring Gerard Butler as Spartan king Leonidas and Lena Headey as Queen Gorgo. When King Leonidas and his 300 Spartan warriors fall to the overwhelming Persian army at the Battle of Thermopylae, the fearless actions of the noble fighters inspire all of Greece to stand up against their Persian enemy and wage the battle that would ultimately give birth to the modern concept of democracy.
