Two weeks ago, we learned that Chinese-government officials were allowed on the set of Iron Man 3 to “monitor filming,” and now more news on the country’s influence on the forthcoming Marvel title. To appeal to the world’s fastest-growing film market, the studio will release a slightly altered version of the Robert Downey Jr. superhero feature in China—one with additional footage approved by director Shane Black that, he says, he expects will “filter back” to the U.S. for stateside fans’ ultimate enjoyment. During a recent Iron Man 3 junket covered by /Film, the filmmakers were tight-lipped about the alternative storyline to maintain “an element of surprise,” but discussed how they juggled production of the two versions.

“I was busy doing the American version while we were simultaneously obtaining footage for the Chinese version,” Black explained, “so I got a sense of what was going on. I was asked to look at and had a chance later to approve the footage, so now you’ve got these two versions. I’m just thrilled that we got the opportunity to work with what is one of the single fastest emerging box office environments in the world, which is China, where they build theaters so quickly now.” He also added, “The Chinese version will have an interesting surprise.”

One of the scenes filmed exclusively for the overseas audience will feature popular Chinese actress Fan Bingbing. /Film hypothesizes that the slightly altered storyline could relate to the movie’s central villain, the Mandarin, a Chinese-born character created by Stan Lee, who will be played by Ben Kingsley inIron Man 3.

Iron Man 3 is not the only production bowing to China’s box-office influence lately. Paramount changed a minor plot point in its upcoming Brad Pitt apocalypse movie World War Z to avoid ruffling feathers in the world’s second most lucrative movie market. Starting in June, a Chinese reality TV show will begin a casting search for four actors to appear in Michael Bay’s next Transformers installment.
