Far less common, however, is a studio making two different versions of the same movie for its theater releases in different countries, which is about to happen when Iron Man 3 opens in the U.S. and China on May 3.

In an announcement from Marvel Studios today, the company revealed that the Chinese version of the movie will include “significant Chinese elements” created in co-operation with Chinese media company DMG, which is distributing the movie in China.

“Both versions of the film include Iron Man 3 footage filmed in Beijing in December,” the announcement explains, but “the Chinese version of the film will also feature a special appearance of China’s top actress, Fan Bingbing, and will offer specially prepared bonus footage made exclusively for the Chinese audience.”
