Last night, ABC aired Marvel Studios: Assembling A Universe, which brought an exclusive sneak peek at Avengers: Age of Ultron. Not only did we get to see concept art of Quicksilver and Scarlet Witch (which gets animated here), this latest video clip from the special also brings us a behind-the-scenes look at the Hulkbuster scene eagerly awaited by fans. Watch as director Joss Whedon and producer Kevin Feige discuss the intricate making of the movie, how certain new charactes will be implemented into this universe, and maybe even a surprise or two. We also have a final piece of concept art from the sequel itself.
