The latest featurette from Warner Bros.' 300: Rise of an Empire offers new insight into the villains Artemisia (Eva Green) and Xerxes (Rodrigo Santoro). We learn that Artemisia's entire family was slaughtered by Greek soldiers, causing her to train with the Persian army as she vows to get vengeance. This action-packed follow-up also shows the transformation of Xerxes into a God-king, through the manipulation of Artemisia, giving this villain a proper origin story. Check out this featurette with new footage and interviews from producers Deborah Snyder, Gianni Nunnari, Zack Snyder, Gianni Nunnari, director Noam Murro, Eva Green and Rodrigo Santoro, before the battle begins in theaters March 7.
