Vietnamese mixed martial artist Cung Le will be appearing in The Grand Master.
Earlier this month the former Strikeforce Middleweight Champion spoke of the possibility of working with director Wong Kar-wai:

Any additional Hollywood plans at the moment?
CL: I just got an offer to go to China before this shoot, and they’re willing to work around my schedule, to work with the famous director Wong Kar Wai. He’s a pioneer, and a very interesting artist.
