Henry Cavill is still working hard as the eponymous man of steel in Zack Snyder’s new Superman film, but the Brit star must be enjoying a little downtime, because he’s eying his next project, period epic The Great Wall.

Edward Zwick, of The Last Samurai, is already in place as director, having written the screenplay with Marshall Herskovitz.  It's based on a story by World War Z scribes Max Brooks and Thomas Tull.

Plot details are light, but Variety report that the film will look into the mystery behind how China’s Great Wall was built in the 5th Century BC.

No word yet on who Cavill would play, though we assume he'll get to fling a few fists in the process. With Zwick behind the camera we should definitely expect some action, not to mention beautiful period furnishings.

Cavill may still be pumping iron as Superman, but we won’t get to see the finished film until Man Of Steel opens on 14 June 2013.
