Marvel Entertainment has released a new video interview with Avengers: Age Of Ultron screenwriter and director Joss Whedon.
In it, Whedon discusses how James Spader ("The Blacklist") brought the film's main villain to life. "He has that voice, that very terrifying 'I own everything' maleficent evil voice and then suddenly get very peevish about something," Whedon said of Spader's voice performance. "He can go from very intense to very comedic, and get there on a dime beautifully."
In the comics, Ultron's face isn't expressive, but for the film "his face is articulated." To pull that off Spader actually was on set wearing motion-capture gear. "It was a nightmare for poor James because he wears glasses, which he could not wear," Whedon explained. "And he was wearing a helmet with two cameras with light on them shining into his eyes and he has to go around set like he is an eight foot robot quickly and confidently over these jagged sets."
