What we're going for, in those humorous moments, is the absurdity of it all. The craziness of the night manager offering them an umbrella in the height of what is a horrible disaster was like, "What?!" That's Andy Greenfield, and he nailed the audition. He's the sweetest guy in the world, as is often the case with those guys, but on camera, he's so creepy that a lot of us kept saying, "You know, Andy, don't look at us like that anymore, okay? You're scaring us."

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.

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'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.

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.

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.
