Marvel has announced that a different version of the third "Iron Man" will be screened in Chinese theaters at a yet undetermined date.
The Chinese version of the film will include a special appearance by China’s top actress, Fan Bingbing, and will offer specially prepared bonus footage made exclusively for the Chinese audience.
Meanwhile, Marvel's Kevin Feige has explained why Don Cheadle's War Machine armour has been redesigned to reflect the 'Iron Patriot' look:
"A few years ago they created a suit called the Iron Patriot, which was an advanced Iron Man suit painted red, white and blue with a star on it.
In the comics it's a different character that wears it and utilizes it. But we really loved that image. And coming off of 'The Avengers' where you have Captain America, we thought it would be fun if the United States wanted to have their own version of that.
Of course, Captain America works for the United States, but he's more of an Avengers hero, which is why [the government] takes War Machine and rebrands him as the Iron Patriot."
Finally, U.S. cinemas are planning an "Iron Man Marathon" on May 2nd which will include the first two movies, "The Avengers," and a 9pm screening of the third film.
