The news that James Spader would play Ultron in the upcoming Avengers sequel was about as well received as any casting news for a comic book film has any hope of being in the social media age. Still, the announcement did leave some wondering how exactly Spader would be playing the role. Would he simply be a voice actor or would the Emmy-winner be performing on set in some capacity? In an interview with Inquirer Entertainment, Spader puts the question to rest.

While promoting his new NBC series The Blacklist, Spader was asked about preparing for his role as the Avengers antagonist:

I have spoken to Joss Whedon about it. And yes, actually, just this weekend I went in for them to take very extensive photographs, head scans, body scans, and all kinds of things in preparation for figuring out how the hell I’m gonna fit in this Ultron character!

 

 

So while the implication is that it isn't exactly determined how Spader will play Ultron, it seems like it will be very similar to the motion-capture strategy Whedon and company employed in creating Hulk from Mark Ruffalo in the first Avengers film. All things considered, that worked out pretty well.

Avengers: Age Of Ultron begins filming in January, and arrives in theaters May 1, 2015.
