Scarlet Witch & Quicksilver Look Up To James Spader's Ultron In New Avengers: Age Of Ultron Featurette

Marvel Entertainment has released a new mini-featurette showing behind-the-scenes footage of James Spader wearing a motion-capture suit for the nefarious Ultron.

When the Maximoff twins (Elizabeth Olsen and Aaron Taylor-Johnson) filmed their scenes with Ultronthey had to look three-feet above James Spader's head, where bright red dots were used as a reference to where the maniacal robot's eyes would be. Though, Elizabeth admits that it was difficult for her and Aaron to keep their eyes fixed above when Spader was delivering a tremendous performance right in front of them.

"I wanted not just a new perspective, but a new visual language," director Joss Whedon explans why he chose to have Scarlet Witch and Quicksilver appear in the Avengers sequel. "She can get inside their heads. He can move, so everything is super-slowed down. That's going to give me a language I couldn't have used in the first one."

Check it out in the video below.

The epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth’s Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to the Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

Marvel's Avengers: Age of Ultron coming to 3D Digital and Digital HD on September 8 and to 3D Blu-ray, Blu-ray, DVD, Digital SD and VOD on October 2!
