In Warner Bros.' action sequel 300: Rise of an Empire, the Persian king Xerxes (Rodrigo Santoro) amasses his soldiers to wipe out the rest of the Greeks at Athens, with the help of his evil ally Artemisia (Eva Green). Following the third trailer that debuted yesterday, the studio has released a new banner, which shows the epic size of Xerxes' devoted army. Standing in their way is General Themistokles (Sullivan Stapleton), who tries to unify all of Greece in battle against this tyrant, who will stop at nothing until Athens burns to the ground. Director Noam Murro's fantasy adventure hits theaters March 7.
