Once again saying things about The Avengers he probably shouldn't, Samuel L. Jackson has confirmed the rumor Elizabeth Olsen will be playing Scarlet Witch. "I don't think we begin shooting before March of next year," Jackson told the Wall Street Journal of Avengers: The Age of Ultron. "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." The one thing we do know: she'll probably be into Stevie Nicks.
