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.

And, what we've allowed ourselves to become - and this is part of Chris' ideas - is complacent, in allowing our lives to be taken over, or at least in allowing that kind of scrutiny into our lives. We've given up a little bit of that, and this is the existential nightmare of all of that. What happens when you suddenly find out that people have been watching you, with a purpose?

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?

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.

Casting is really weird. Honestly, when Alan Ruck's name came up - and I've worked with Alan before - I went, "Yes, he's perfect." He came in and read for us, which was really sweet of him because he didn't have to, and he nailed it in seconds. We knew exactly who we had. That stuff is really good and fun.

It was tough to write. We had the shadow of "Lost" hanging around and I just kept saying, "Guys, we need to take a really wide birth around 'Lost.' We're going to get lots of comparisons anyway, but we need to prove, within a couple episodes, that it's not 'Lost.'"
