Marvel Studios is preparing different version of Iron Man 3 for its impending release in China, which will feature footage not shown in the United States or anywhere else in the world. The new scenes will include an appearance by Chinese star Bingbing Fan and other exclusive footage shot specifically for the Chinese market. Here is Marvel Studios' official statement regarding the Chinese version of Iron Man 3.
"Marvel Studios and DMG announced that a Chinese version of Iron Man 3 will be released in China on a date to be announced in the near future. DMG, a Chinese media and entertainment company, collaborated with Marvel Studios on the Chinese elements in the film, and is marketing and distributing the film in China. While Marvel and DMG have decided not to apply for co-production status in China, the film includes significant Chinese elements. Renowned Chinese actor Xueqi Wang will appear in both the studio's Chinese version of the film and in its international and domestic US version. Both versions of the film include Iron Man 3 footage filmed in Beijing in December. The Chinese version of the film will also feature a special appearance of China's top actress, Bingbing Fan, and will offer specially prepared bonus footage made exclusively for the Chinese audience. Marvel Studios' experience working on this film with Bingbing Fan and Xueqi Wang and in shooting in China has been very positive and has created a springboard for future collaboration with China's talented stars and its growing film and television industry. The Iron Man cast and filmmakers look forward to bringing Iron Man back to China."
It isn't known if this bonus Chinese footage will be made available on the American Blu-ray and DVD release of director Shane Black's superhero sequel.
