Re: Why no Mandarin
I think, like has been said it has a lot to do with Political Correctness, Mandarin may not be seen in a good light in the asian markets,where these movies make there money, especailly China.
I do agree that Mandarin didn't start out Mystical until the 90's when Marvel decided to turn him that way, but in the end even his 10 rings of power where Technology based.
I think, if they use Mandarin, use him in away that show's he's causing all of Starks problems, that man behind the screens, then use him in the third film as that main villian. just an idea anyway.
