The casting of James Spader as the voice of the titular baddie in The Avengers: Age of Ultron could also provide a nugget of plot detail: Perhaps Ultron is out to destroy humanity because he’s just so over people.
Spader is known for playing some cold characters, and among the constants in his repertoire of acting skills is an amazing sense of condescension; it simply drips from every word coming out of his mouth and radiates from every pore of his body — so perhaps it’s a good thing Ultron is expected to be CGI. (Will Spader perform the motion-capture, or leave that to a pro? Andy Serkis and Doug Jones, call your agents…)
Imagine Ultron, molded from adamantium, stalking around NYC, delivering withering put-downs and sarcastic comments that degrade and demean Earth’s Mightiest Heroes as he heaps shame and humiliation on them.
Or, maybe Spader’s Ultron will be more like Mr. Grey, his character in 2002’s Secretary — and the indestructible robot will insist that Black Widow (Scarlett Johansson) spank him!
