IGN: How many variations on that storyline did you discuss, and how did you come to focus on what you did?

Filoni: Well, we all knew it would be a challenge to stretch it for four episodes, that?s for sure. Brent Friedman took up the task, and I thought that was really brave, because some of them were just concepts that we had never done before. When you consider the second episode as largely a kind of existential exploration into the void of nothing -- and yet we all really like that episode. It was a visual challenge because there wasn?t a lot on screen. That?s actually in some ways more challenging than a completely congested Coruscant. The one with the clone I knew would be a very strong episode. I think after we had pitched it out, there was some debate. We actually wanted to include Gregor more, but it just wasn?t really how the stories were structured. I had to actually adapt the story to make it believable that maybe Gregor survived the explosion at the end, which I believe is actually the case. But it was a big challenge.
