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.
"Hi I'm Scarlet Witch, just casually looking phenomenal and saving Hawkeye's life by holding up this forcefield."
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.
