Joe Kosinski: Yeah, I did that VFX test, that three-minute piece before the script was written, so there was no script for the movie when we showed that at Comic-Con. So then the script had to be written, and I kind of hinted at the narrative of the story I was interested in in that VFX test piece. But then the script had to be written to it.
So the script was written by two writers from this television show Lost named Adam Horowitz and Eddie Kitsis. They’re the screenwriters, but just because of the nature of this movie and them needing to understand the world and these set pieces it was a collaborative process to get this script written. Because you can’t just send them off and say “Write a script for Tron.” It had to be done in conjunction with the Art Department.
So while I was building sequences like the disc games or the light cycle races and all that stuff that had to be built upfront, the script was being written in parallel to that. But I am not a writer myself so I can’t take any credit for actually writing any part of the script.
