Olsen noted that when Joss Whedon offered her the role, he said "[wh]en you go home and Google her, just know you will never ever have to wear what she wears in the comics",[15] and, in keeping with this, Wanda's comic book costume was ignored in favor of more casual clothing. She first appeared, as well as Quicksilver, in a mid-credits scene of the 2014 film Captain America: The Winter Soldier as a prisoner of Baron Strucker (Thomas Kretschmann).[16] Scarlet Witch became a supporting character in the 2015 film Avengers: Age of Ultron, where the siblings initially conspire with Ultron (James Spader), a reflection of their initial villainous roles in the comics, but later defect to the Avengers.[17][18] Quicksilver dies in the ensuing conflict while Wanda goes on to become a member of Captain America's Avengers. She appears in the 2016 film Captain America: Civil War.[19] Both Olsen and Aaron Taylor-Johnson signed multi-picture deals.[20] Olsen reprises the role in the 2018 film Avengers: Infinity War, its 2019 sequel Avengers: Endgame, and the 2022 film Doctor Strange in the Multiverse of Madness.[21][22] In the films, her powers are telekinetic and telepathic abilities, which she gained by volunteering as a test subject in Hydra experiments to create supersoldiers, by exposing her to the Mind Stone.
