Zack Snyder directs this faithful adaptation of Frank Miller's (Sin City) graphic novel about the storied Battle of Thermopylae, a conflict that pitted the ancient Greeks against the Persians in 480 B.C. The film, which blends live-action shots with virtual backgrounds to capture Miller's original vision, co-stars Gerard Butler, Lena Headey, David Wenham, Vincent Regan, Rodrigo Santoro and Dominic West.
