Chinese-American actor Tom Wu to star in Ra.One

Apart from Shah Rukh Khan, Kareena Kapoor and Arjun Rampal, Anubhav Sinha's sci-fi extravaganza Ra.One will also star Chinese-American actor Tom Wu. SRK even tweeted recently about Tom joining the cast of his home production. Said the superstar, "a big welcome to Tom Wu in the film cast. He is so humble & such a sport...really nice to have him on board."

For the uninitiated, Tom Wu is a martial arts expert who has starred in films like Revolver, Shanghai Knights and Batman Begins. Considering that Ra.One also has its fair share of heavy duty action, one can be rest assured of seeing Tom Wu kick some butt in this flick too.
