Re: Changing the roster for Avengers 2?
Returning: Captain America, Hulk, Iron Man, Thor
Leaving: Black Widow, Hawkeye
They're going to stick with characters that are known for the movies and throw a lot of cannon out the window because it just gets too out there. They'll stick with the formula that proved successful with The Avengers.
I'd also love to see a movie focusing on Black Widow and Hawkeye in the style of a thriller. It has a lot of potential and would be cool to see. Even if they don't appear in Avengers 2, we need to see them again sometime.
