The first Hulk movie definitely had the best teaser I've ever seen for a comic movie, one of the best for any movie actually. I remember the reaction to it, as most in attendance had no idea a Hulk movie was coming, and didn't know what the trailer was about until his eyes started transforming. The only other trailer I witnessed anything like that for was the Matrix Reloaded, which drew an ovation (It's funny how these things worked out huh?). I think they can do something similar with this one, because outside of the hardcore fans, not too many people know about this yet. Furthermore, I don't think people would expect Norton to be in this movie at all, speaking in terms of the general audience. I mean we, the fanboys, barely know anything about this film yet, a good trailer will catch almost everyone off guard, and hopefully help to distinguish the movie as something seperate at the same time...
