<Li> James Spader as Ultron : An artificial intelligence repurposed by Tony Stark and Bruce Banner for a pilot peace program that is overwhelmed with a god complex , and now desires to pacify the Earth by eradicating humanity . Director Joss Whedon stated that Spader was his `` first and only choice '' for the role , because of his `` hypnotic voice that can be eerily calm and compelling '' while also being very human and humorous . Feige clarified that Spader 's face and body were motion captured `` to create a whole performance ... We did not hire James Spader to do a robot voice . '' Extensive scans were taken of Spader 's head and body in preparation for the role . About the character Whedon said , `` He 's always trying to destroy the Avengers , goddamn it , he 's got a bee in his bonnet . He 's not a happy guy , which means he 's an interesting guy . He 's got pain . And the way that manifests is not going to be standard robot stuff . '' Whedon added that Ultron is `` not a creature of logic -- he 's a robot who 's genuinely disturbed . We 're finding out what makes him menacing and at the same time endearing and funny and strange and unexpected , and everything a robot never is . '' Whedon compared Ultron to Frankenstein 's monster , saying , `` It 's our new Frankenstein myth ( ... ) We create something in our own image and the thing turns on us . It has that pain of ' Well , why was I made ? I want to kill Daddy . ' '' Spader called the character `` self - absorbed '' and added , `` I think he sees the Avengers as being part of a problem , a more comprehensive problem in the world . He sees the world from a very strange , ( biblical ) point of view because he 's brand new , he 's very young ... He 's immature , and yet has knowledge of comprehensive , broad history and precedent , and he has created in a very short period of time a rather skewed worldview . '' Spader elaborates , `` He truly is an artificial intelligence with absolutely no censorship at all , no parameters really ... he 's got too much power , too much strength and speed and size , so he 's a very dangerous child .
