James Spader may be doing interviews to promote NBC’s The Blacklist, but the acclaimed actor is still going to face questions about his role in Avengers: Age of Ultron. He’s been cast as the film’s title villain, Ultron and recently said that pre-production work has already started.

While chatting with The Philippine Inquirer, Spader said that he already started conversations with writer/director Joss Whedon about how they will approach Ultron.

“I have spoken to Joss Whedon about it,” he said. “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!”

According to FlixAndBits, Spader explained to The U.K. Independent why he took on the role.

“I think it'll be a lot of fun and it's incredibly nostalgic for me,” Spader said. “When I was a kid my best friend had trunks of comics and I didn't have any so I used to love going for sleepovers at his house. Also I have three sons and two of them have a great interest in comics so they're excited I'm playing the role.”

Spader was cast as Ultron last month. The Avengers: Age of Ultron is scheduled for release on May 1, 2015. But you can see spader much sooner on NBC’s The Blacklist, which airs every Monday after The Voice.
