I know he was in the first couple of issues of the 616 universe. But...ok...so you guys are saying you would rather want Marvel Studios to make an Avengers film where the Hulk/Banner won't be as big of a character as say Captain America, Iron Man, and Thor OR would you want another solo Hulk film? For a bunch of Hulk fans I'm truely shocked at this. The only team that would give the Hulk the screentime he deserves in a film would be a Defenders film (Unfortunatly I dont see Pantheon doing anything...I miss those guys in the comic!! I want Ajax back!!).Hulk was in the avengers(read Essential Avengers volume 1) in fact he was the reason Avengers were formed, the Ultimates and made them famous so he is basically an important part of the avengers
(Just look way back when he was crusiing around in space with rocket raccoon and the film maker (Her name slips my mind now))
