Elizabeth Olsen is heading for her superhero movie debut in Marvel‘s 2015 sequel The Avengers: Age of Ultron. A source close to the situation tells Deadline she’s all but sealed for the pic and that her deal is “just a matter of formality before it’s done.” Marvel isn’t officially talking specifics but Samuel L. Jackson, the Avengers’ Nick Fury, confirmed Olsen’s casting as the Scarlet Witch during an interview with the WSJ. Olsen next appears in FilmDistrict’s Oldboy and is repped by The Gersh Agency, Brillstein Partners, and Sloane, Offer, Weber & Dern.
