Jamie Blackley Cast In '300: The Battle Of Artemisia'

Briefly: The cast is shaping up for Noam Murro's prequel to the unexpected blockbuster hit 300. The film, 300: The Battle of Artemisia, is scripted by Zack Snyder and Kurt Johnstad based on Frank Miller's graphic novel Xerxes, and we've had a couple major cast announcements in the past few weeks: Sullivan Stapleton is playing Greek warlord Themosticles; Rodrigo Santoro is returning to play the Persian leader Xerxes; and Eva Green will be the title character Artemisia.

Now Jamie Blackley, recently seen (by some) in William Monahan's London Boulevard and soon to be on screens in Snow White and the Huntsman, has been cast in a role that is described as one of the co-leads of the film. He'll be Calisto, "a teen whose desire to become the heroic man/soldier his father was leads the 16-year-old to become a leader of a small band of soldiers." [Deadline]
