We had heard the Saoirse Ronan was up for the role of The Scarlet Witch in The Avengers: Age of Ultron, and all reports indicated that she was into it. But perhaps that fell apart, or maybe scheduling didn't work out, because Bleeding Cool is reporting that she's not taking the part and that Joss Whedon and Marvel Studios are turning to another actress. The site claims Elizabeth Olsen is up for the role.
Olsen is great - check out the brilliant Martha Marcy May Marlene and Kill Your Darlings for proof - but is she right? Or rather is the movie right for her? I know that she has been courted by other high-profile superhero movies (is this Avengers offer a form of cinematic cockblocking?), but I have also heard she was a bit lost on Godzilla, which she recently finished filming. Are big budget spectacle movies just not her thing? Whedon does them differently of course - this would be much more character-oriented than your usual action picture - but perhaps that experience has left her gunshy.
I like Olsen for just about any role, as I think she's one of the most talented actresses of her generation. So I'm all for it, if it comes to pass. Someone get working on a Martha Marcy Wanda Marlene mash-up right now.
BTW - my favorite part of the Bleeding Cool article is the claim that the role will demand a European accent. Not many people realize this, but Quicksilver and the Scarlet Witch are actually from a fictional Eastern European nation known as Transia. Most studios wouldn't even bother including that detail in their adaptations, but Marvel Studios clearly is.
