OMG OMG IT'S HAPPENING - here's our first look at Scarlet Witch and Quicksilver!
Scarlet Witch and Quicksilver (played by Elizabeth Olsen and Aaron Taylor-Johnson respectively), are mutants and Magneto's estranged children in *Marvel comics. Scarlet Witch is a magic user, and has the power to manipulate realities. Quicksilver, her brother is, duh, super fast.
*However since Fox owns the movie rights to X-Men, there's very little chance Magneto will even be alluded to in Age of Ultron, and a different actor (Evan Peters) will be starring as Quicksilver in X-Men: Days of Future Past.
They look pretty great in action tbh.
Actually she's probably on the offensive here. Annihilating Ultron's minions is all in a day's work.
Also we get a look at what could be the beginnings of Ultron. Minus the puffy jacket and plus a massive amount of CGI of course.
The titular villain is an advanced AI that controls an artificial robotic body.
