SRK ropes in Tom Wu for 'Ra.One'

Bollywood superstar Shah Rukh Khan has roped in Chinese-American actor Tom Wu for his home production Ra.One.

"...a big welcome to Tom Wu in the film cast. He is so humble and such a sport... really nice to have him on board," Shah Rukh, 44, posted on his Twitter page.

Tom Wu, a martial arts expert, was earlier seen in films like Revolver, Shanghai Knights, Batman Begins and Tomb Raider II.

According to earlier reports, action legend Jackie Chan was approached for a role in the action flick.

Ra.One will also see Arjun Rampal and Kareena Kapoor. American singer Akon too is part of the crew as he recorded a song for the movie.

The film is expected to release in 2011. Shah Rukh, who is currently shooting for the film in London, is a little unwell.

"Antibiotics have sucked all energy out of me. Throat feeling better now... can go on the sets and make some noise to feel important hopefully," he wrote on his Twitter.
