James Spader Does Motion Capture For Ultron In Avengers: Age Of Ultron Featurette

Marvel Entertainment has released a new featurette for Marvel's Avengers: Age of Ultron showing James Spader's process of crafting Ultron's performance.

Chris Evans ('Captain America') and Mark Ruffalo ('The Hulk') marvel at their good fortune; witnessing an actor, who they clearly admire, performing right before their very eyes. Spader does his own marveling as current motion-capture technology allows him to instantaneously view his performance on Ultron's much larger frame.

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!
