Detective Dee and the Mystery of the Phantom Flame star Andy Lau is reportedly in negotiations to join the cast of Iron Man 3. If cast, he will play an old friend of Tony Stark and according to the report the character represents "China’s technology sector – and will use China’s armored heroes to HELP Iron Man defeat 'The Mandarin' who is seen as a terrorist against both the US and China." This is the first time I've heard that The Mandarin would play a role in the film. I've heard other reports saying that Mandarin wouldn't be the main villain.
Lau is a badass, and I hope he ends up officially getting cast in the movie. He would be joining Robert Downey Jr., Gwyneth Paltrow, Don Cheadle, Ben Kingsley, Guy Pearce and Jessica Chastain. Shane Black is directing the third installment of the franchise which is scheduled to be released on May 3rd, 2013.
