Am I the only one who wishes that they would use unknowns for the characters instead of getting "name" stars? I know it's so they can get that elusive "non comic fan" to go to the movies, but for me it just destroys the illusion. What I mean is, I don't see Tony Stark and Nick Fury, I see RObert Downey, Jr. and Samuel L. "I'm in 316 movies this year" Jackson. (And yes, I know Ultimate Nick Fury was based on Jackson)
I don't know, I just think that the characters are what we should be going for, but by putting in well known actors it turns into an (insert the name of the actor here) Project instead of an Avengers movie.
