Re: Avengers 2 News, Rumors, Etc. Pictures until release...
Apparently the reason Saorise Ronan turned down the Scarlet Witch role is because she's being considered for a role in the next Star Wars movie.
I'm guessing Joss and JJ had a meeting of the minds. Maybe Disney thought Ronan would suit better with Star Wars, and Olsen with Avengers.
Star Trek 2009 is Canon. It is in an Alternate Reality.
Star Trek 250+ million or Bust!
