One of the major issues that faces every Hollywood studio - especially those who make blockbusters - is trying to account for the various tastes and restrictions of different boards of censors around the world. What's fine in America may not be fine in China. Sometimes, what's fine in the United Kingdom isn't fine in America! Because of that, big movies often end up with many different editing cuts, all done to please a different set of censors.
At one point, India wasn't going to approve any version of the film. They considered it to be too violent and too gory and refused permission for it to be screened in their cinemas. That all changed when India's Home Minister was sent a copy of the movie to watch himself at home. Needless to say, he loved it, understood its importance, and overturned the decision to ban it.
