Yes, worldwide. I'm told 75% of the people who have seen it in foreign countries had to see the 2D version (not many 3D projectors in these countries) so I wonder what the big draw for them is?
Probably the hype and the fact that it is from the director of Titanic. It certainly isn't because of the star power of the film's actors. And its an entertaining movie. One that people have seen in other guises a few times, however.
