It's not unheard of, in the course of life, that if there's enough interest in it, we could consider going a second season or doing another chapter. I keep looking at it as books in a series, and this season is the first book.

I ended up working on "Chicago Hope" and other things, but always with the idea that, eventually, I would want to take what I'd learned in character drama and try to apply that to the genre that I love, which is science fiction and "The Twilight Zone" type mysteries.

What we were trying very hard to do, just in the way we shot it, was to make it feel as if we're in that environment ourselves, just so we can get a grasp on what it is. A lot of our influence was about getting stuck on a level on any of those video games, where you find yourself caught and you can't get out, and it's maddening. We talked a lot about that.

I'm not saying that I'm the grand genius that came in on a float and made it happen, but they liked my pitch. I was on my way to a camping trip with my daughter when my agent called and said, "This thing came up and it's really wild and crazy, do you want to read it?" And, I said, "Yeah, why don't you just send it to me? But, I'm going on this camping trip, so I probably won't be able to read it until I get back."

I feel confident that we will have a beginning, middle and end, in this season, and it was wise of NBC to then call it what it really is, which is a mini-series. "24" is a really good example, in that there was a definitive beginning, middle and end for the first season. They had a slightly different format than we have, but the second season just retained Jack Bauer and a few other players, with the same basic format and idea, but it was a completely different show.

Yes, there's a lot of crazy stuff going on there, but it still comes down to those seven people. What are they going to do? How are they going to deal with everything?
