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.

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?

When we finally had a cast and could see what they could do, here was an opportunity to go back and modify things. We didn't actually do that much modifying, but we did enough to make it feel as if they fit in their own skin, and we got a lot of good input from them. They're a terrific cast. They worked really hard.

I feel confident that it will always keep everybody guessing, and yet not in that weird, maddening way where it's like, "Oh, come on, guys!" I think you will be freaked out by the end. I really do. I don't think you'll see it coming at all.

Suddenly, I realized how tough trying to structure a story like this is. It was a lot of work. The one big advantage that we had was that we had eight scripts written before we started shooting, or even started casting. We had a really good opportunity to look at it and figure out where we were going to go and how to do it. Once we got a cast, which I love, then we started doing some revisions to make sure that they fit into it.

There's little things like that, that we paid a lot of attention to. We don't always know how to bond together to get help or to do something, and our attempts are often awkward, selfish or weird. We talked a lot about how to open things up.
