the thing about this cross over is that different companies own the movie rights to these characters, and they are just too reluctant to work together for the cross overs like hulk/wolverine fantasticfour/avengers xmen/avengers things like that to happen. why wasn't spiderman in the avengers? he lives in New York after all. the reason: a different company owns him, its one of the biggest reasons a lot of these movies are so different from the comics, some things just CANT happen because the characters needed aren't available. sorry to dash your hopes bro :/ hulk is my all time favorite, ive read up on everything I could find about him and his fights with wolverine never fail to entertain me. I could only imagine how amazing it would look on the big screen but im sorry to say it just wont happen.
