James Spader, el autor que lo interpreta, habla sobre su personaje:
”In many ways he's a child, this character, because he's a brand new being who's just come to be. And yet, through artificial intelligence, he has an incredible capacity for knowledge. So he's a very powerful, smart child. There's a humorous aspect to him, which is something that drew me in from the very first conversation I had with Joss.”
"Ultron takes abrupt turns in scenes. Yes, he is psychopathic. He's really batshit crazy!"
