It was rumored a few months ago that Andy Lau would be joining Iron Man 3 as an ally of Tony Stark, but he quickly backed out of the position. We've learned today from Mtime.com (via Chinesefilms.cn) that actor Wang Xueqi will be taking on the role that Lau was circling and there might be more to it than we first thought.

Xueqi will be playing Chen Lu. If you're up on your Iron Man mythology, you will recognize that name as the civilian alias of Radioactive Man. Radioactive Man has worked for the Mandarin on many occasions, who we learned at this year's San Diego Comic-Con will be the primary antagonist in the film. With that in mind, it's not too much of a stretch to think we will see Radioactive Man on the big screen next May.
