Samuel L Jackson confirms Elizabeth Olsen 'Avengers' role

Samuel L. Jackson does play S.H.I.E.L.D. honcho Nick Fury. So why shouldn't he be breaking casting announcements for The Avengers sequel?

Jackson let slip to The Wall Street Journal that Elizabeth Olsen would be joining the cast of The Avengers: Age of Ultron.

"I don't think we begin shooting before March of next year. 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, but I don't know what she's doing, if she's on the inside or the outside. I haven't seen a script," said Jackson.

The Internet has been buzzing ever since, seeing this as confirmation that Olsen will play the long-discussed role of Scarlet Witch in the sequel to the superhero hit.

It's another big role for indie-fave Olsen, the younger sister to Mary-Kate and Ashley, who also stars in the much-anticipated Godzilla remake due out in 2014.

Jackson, who was discussing his Nick Fury cameo on ABC's Marvel's Agents of S.H.I.E.L.D., did not confirm who would play Scarlet Witch's mutant brother Quicksilver, long rumored to be Kick-Ass star Aaron Taylor-Johnson. Perhaps the Journal can throw in a follow-up question.
