Weren't we also introduced to Dr. Connors? He's the guy that eventually becomes the lizard when trying to regrow is arm right? So Harry Osbourne's Green/Hob Goblin, Jameson's son and Doc Connors. Were we introduced to any other potential villians in the first two movies?
That would be killer, the issue with Thanos on the cover saying come and get me, one of my all time favs. Still there would have to be waaayy to much involved for the movie people to get all of the action and drama of that series. Personally I'd like to see an "Age of Apocalypse" x-men movie but it'd probably have to be far too violent.
