Spencer Douglass posted an article on his blog detailing his experience working on Man of Tai Chi. Mr. Douglass is a producer. He went along to the shoot with a friend to help out on the aerial helicopter shots and ended also doing other work on the film. You can read about his experiences including working through the typhoon on his blog.
