Yes, Iron Man is Marvel comics while the Dark Knight is DC comics. The two biggest rivals in the comic book industry. Yea, who knows why the Incredible Hulk isn't getting enough promotion, but I don't know why. Yes, every movie of their will at least recoup what it has lost, if not more. The Dark Knight will be really good but I am thinking Iron Man might do better, what gives the edge to the Dark Knight is that it already had a film come out. Also, Batman is one of the most popular superheros of all time.
