IGN recently spoke with Joss whedon about Agents of SHIELD. In that interview, Eric Goldman, got Whedon to divulge that the children of Magneto, The Scarlet Witch and Quicksilver, will be in fact in The Avengers sequel. Here is what Whedon had to say:
“You know, they had a rough beginning. They’re interesting to me because they sort of represent the part of the world that wouldn’t necessarily agree with The Avengers. So they’re not there to make things easier. I’m not putting any characters in the movie that will make things easier.”
Whedon has stated that Saoirse Ronan (Hannah, The Host) is the prototype for the Scarlet Witch. Who do you think you play the Scarlet Witch and Quicksilver?
