ultronWhen James Spader was first cast as the antagonist Ultron in Marvel’s The Avengers: Age of Ultron, it was clear that his hypnotic voice had a lot to do with it. There’s a quality that seems to fit perfectly with an A.I., one that isn’t friendly like J.A.R.V.I.S.

It turns out that Spader won’t just be voicing Ultron; he will also provide motion capturing, according to Marvel Studios president, Kevin Feige.

“Well, I think it will be more than a voice role — we’ll be capturing his face and his body to create a whole performance. He’s a very unique and incredibly exciting and unpredictable actor. And Ultron in the comics is a robot, but what’s cool about him in the comics — and certainly how Joss Whedon is interpreting him for the movie — is that he is much more than just a robot. That he’s infused with much character. And I don’t want to say too much, but you can imagine James Spader will be very dynamic in his portrayal of this character.”

It’s evident that Spader has an incredible, and sometimes menacing presence, and it’s exciting to see how he’ll bring Ultron to life on the big screen.

The Avengers: Age of Ultron is scheduled to dominate theaters May 1, 2015.
