Avengers: Age of Ultron introduces a host of exciting new characters to the Marvel Cinematic Universe, chief among which are Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen). A brother and sister superhero duo, they side with villainous A.I. Ultron (James Spader) against our heroes.
Take a look at this behind the scenes featurette and get the lowdown on the awesome superpowers deployed by both characters. And if you're thinking that the name Quicksilver sounds familiar, that's because the character appeared in last year's X-Men: Days of Future Past, albeit played by actor Evan Peters.
