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.

Hardly anybody thinks about typing in their social security number as ID. Hardly anybody pays attention to the myriad of security cameras. There isn't anybody that worked on this show that doesn't look at security cameras differently than when they started.

When you're working on a television show with actors, what you hope you're doing is playing jazz with them all the time. You see what they're giving you, so you try to write back to that, and then they play with that, and you get a sense of what is going on. That's just a natural way in which TV series usually work.

What we're really trying to tell, even though it's very much a genre show, is a very human story. Even in this heightened situation, it still comes down to people being people, and dealing with people as people. It really is about the seven people in that town.

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.

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.

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.
