Now that writer-director Joss Whedon has confirmed sibling superheroes Quicksilver and Scarlet Witch will be a part of The Avengers 2, the talk has shifted to casting these roles. Actress Saoirse Ronan recently spoke about rumors that the director is using her as a "prototype" for the Scarlet Witch character. Although she has not officially been cast yet, the actress revealed she would love to take on the role.

"I have heard about it and yes, I would. Yeah, of course I would. I love Joss and I love those films, and I love his handle on them and how he portrayed these kinds of superheroes. I think it's very different from what anyone else has done. So yeah, I'd love to be in it."
