Director Zhang Yimou‘s first Hollywood flick, The Great Wall, will feature Andy Lau,Jing Tian, Zhang Hanyun, Eddie Peng, Lu Han, Lin Gengxin, Zheng Kai, Chen Xudong, Huang Xuan ,TF Boys’s Wang Kaiyuan, alongside Hollywood actors Matt Damon and Williem Dafoe.    They’re really covering all the fan bases, but I’m hoping some of those will be cameo appearances since some of them really can not act.

Plot (script is written in English by a non-Chinese team) as follows per Hollywood Reporter, although Sina also mentions a female general aka stereotypical Asian love interest:

Damon, who is in final negotiations, will star as a soldier who is part of a group of mercenaries traveling to China in order to bring back gunpowder to Europe. When the group is attacked by mystical beasts, the man finds himself in a war between a secret warrior clan and the beasts.
