With Thor: The Dark World hitting theaters in just a few weeks, the cast and crew have been making the press rounds to promote this Marvel Phase Two adventure. Producer Kevin Feige was recently asked about casting James Spader as Ultron in the highly-anticipated The Avengers: Age of Ultron, which closes out Phase Two in 2015. When asked what stood out about his voice, the producer revealed they plan on using motion capture techniques with the actor.

"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."

When asked if the actor will have a robotic voice, the producer responded with this statement.

"We did not hire James Spader to do a robot voice."
