Last night ABC and Marvel aired Marvel Studios: Assembling a Universe in place of Agents of SHIELD. It's a documentary offering behind-the-scenes looks at the upcoming films in their cinematic universe, and as promised it also gave us a first look at concept art for Avengers: Age of Ultron. The images show us the designs for Elizabeth Olsen's Scarlet Witch and Aaron Taylor-Johnson as Quicksilver. We also see Iron Man decked out in his Hulkbuster armor (glimpsed briefly in Iron Man 3) squaring off against, who else, the Hulk.
Avengers: Age of Ultron opens May 1st 2015.
