IGN : James Spader says he decided to return as Ultron without a completed script and knew the trajectory of Ultron within the context of 'VisionQuest'
Interviewer : So, I'm curious what your reaction was when you read the script. What were those discussions like?
James Spader : There was no script. When I had to make the decision to do the show, it was just based on my conversations with Terry \[Matalas\]. The story would have to be very different if Ultron wasn't going to be on the show. So, first I had to discuss whether Ultron was going to be there. In our first meeting, we started working on it together. I knew the trajectory of the show in that very first meeting. And then I knew the trajectory of Ultron within the context of the show in that very first meeting. But then how funny was it going to be and how that was going to be executed. I didn't see until scripts started to arrive and they were better than I even had expected. We were just having such fun right from the very first meeting.
