The movie has been in the works for several years, with Edward Zwick once set to direct and Henry Cavill and Benjamin Walker set to star. The project fell apart after Edward Zwick dropped out in September 2012, but it was revitalized once again in March when Chinese filmmaker Yimou Zhang signed on to direct.
No details have been given for Matt Damon and Bryan Cranston's characters. The plot revolves around how The Great Wall of China was built, and how it was constructed not to keep out the invading Mongol forces, but to stop an evil supernatural force from entering China.
Tony Gilroy (The Bourne Legacy, Nightcrawler) wrote the most recent draft of the screenplay, which was previously worked on by Carlo Bernard and Doug Miro (The Sorcerer's Apprentice, Prince of Persia: The Sands of Time). It isn't known when production will get under way.
