Although that raises the question: hypothetically, of course, would there be any difficulties with incorporating the ASM universe into the Marvel Cinematic Universe? Perhaps the main continuity issue would be the Manhattan skyline, since there was no Stark Tower in ASM and no Oscorp Tower in The Avengers.
Damn, I was hoping that we would not get Spider-man or Wolverine shoved into an Avengers film for at least another 20 years. I had already had enough of Wolverine taking over the X-men movies after X2.
The characters film rights being owned by seperate companies was the only thing stopping that from happening.
