I’m marking this as a rumor because it seems that there’s a lot of drawn conclusions without any concrete declarations, but there’s some sort of interview with The Wall Street Journal featuring Samuel L. Jackson in which he comments to the casting of Elizabeth Olsen in the upcoming ‘Avengers: Age of Ultron’ film. Check out the quote:

我认为我们不开始在明年3月之前拍摄。I know we’re shooting in London, that James Spader is Ultron and going to be the bad guy, and that we added Ms. (Elizabeth) Olsen (who will play the Scarlet Witch), but I don’t know what she’s doing, if she’s on the inside or the outside. I haven’t seen a script.

需要我指出了他说“我不知道她在做什么？......”。当然，他可能只是意味着他并不意味着她是英雄或恶棍，但这会读它的东西......对吗？
