you people are downright silly if you think they should be worried about the franchise. It's been out for a few weeks and after today will be around 470 million dollars. Sure, the studio will want to make more money---but why should this concern any of us? I said it before, we are guaranteed an Avengers movie and Iron Man 3. Seriously, what do some of you people really want? I have already come to the conclusion that some on this thread are taking glee in the "poor" box office numbers of this movie.
Why this movie isn't making insane money? Who knows or really cares? Iron Man doesn't have a large fanbase, it's not really a kid friendly movie (in my opinion), no hearthrobs died during it's making, etc. It has nothing to do with the quality of the movie. If that was the case, then movies like New Moon, Transformers, and Alvin and the Chipmunks wouldn't be making mad cash. Some movies are just phenoms. Iron Man came out of nowhere. Dark Knight wasn't that much better then Begins, yet it made mad dough. Blind Side and Hangover last year made huge money, even though they were nothing special. You people expected this movie to be a guaranteed phenom like Avatar and in the end it is only a blockbuster.
Iron Man 2 has already made more money at the box office then Star Trek did in half a year by the way, for the guy who brought that movie up. It was one of the best movies of last year and made less domestically then some real garbage. There are simply more little children, screaming girls, and Harry Potter fans in the world then there are sci-fi fans and geeks.
