The villain of the second "Avengers" movie will be "very dynamic," according to the president of Marvel Studios.

"We did not hire James Spader to do a robot voice," said Marvel Studios head Kevin Feige, continuing the happy tease of just what Ultron is going to be in 2015's Avengers: Age of Ultron.

According to the Feige, Spader has been hired to provide more than his voice for the Avengers' latest bad guy, who historically -- in the comic books, at least -- has been a particularly malicious cybernetic presence inhabiting robot bodies. Whether "more than his voice" extends to an actual onscreen appearance by the actor remains up in the air, as Feige seems to be suggesting that Ultron might be larger than just one person.
