Anything is possible. I just read an article on a huge spread of predictions for opening weekend. It's not science really and somewhat unpredictable. There's a huge population who cherish the original, but do they care 20 years later. The kids today do not know about the hype and release of the original. They've probably seen it, just not enamoured with it.

I still think it will be a very good opening. I'm biased. ID will probably be one of the few films I go see at the theater
