The co-lead of the Ed Zwick-directed The Great Wall is between True Blood‘s Alexander Skarsgard and Benjamin Walker, who stars in the upcoming Abraham Lincoln: Vampire Hunter. The Legendary Pictures film already has Man of Steel’s Henry Cavill set to star in an adventure film about British warriors traveling through 15th Century China and happen upon the hurried construction of the massive wall. As night falls, the warriors realize that the haste in building the wall isn’t just to keep out the Mongols. There is something inhuman and more dangerous. The picture, based on an idea by Legendary CEO Thomas Tull and Max Brooks, is being made through the Hong Kong-based Legendary East.
