the American cut of the movie, Dr. Wu performs the operation and is never seen again, but the Chinese cut extended the sequence, added a scene where Dr. Wu drinks milk and calls J.A.R.V.I.S. (Stark’s AI) on the phone to pledge his support against the Mandarin, and included a commercial for the milk drink Gu Li Duo at the beginning of the movie. (The Chinese milk market was in turmoil at the time; a major dairy company had just recalled some of its baby formula because of mercury contamination, and so the industry needed to convince citizens to trust milk again.)
