So it looks like Bleeding Cool were on target back in august when they reported that Elizabeth olsen was in talks to play the Scarlet Witch in Avengers: Age of Ultron .
Samuel Jackson is reported to have said to the Wall St Journal
“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.”
So it looks like elizabeth Olsen is in but theres no confirmation on whether she is playing The Scarlet Witch or not but everyones pretty sure thats what she will be doing. Its good to see another female in the team especially a staple of the Avengers such as the Scarlet Witch shes an interesting character and Im sure Joss will have fun with her.
