Just watched the trailer to his upcoming series 十月围城 (The Stand In) (aka Bodyguards and Assassins). It's an action and historical (late Qing dynasty) drama in which he plays two men who look very similar to each other. The trailer doesn't really mention if they are long lost twins, like in Imminent Crisis, or if it's just by chance. Highly recommend Wallace fans to take a look at the trailer.
I'm sad that he has a queue in here though because I think he looks so much better with hair. Still very good looking despite being half bald.
