I've always been a sci-fi geek, and I've always loved it. It's my favorite genre of all. The irony of ironies is that, in my early career, I just really never worked in it. "Star Trek" was very interested in me, partially because I did "From the Earth to the Moon," and I was really interested in them, but the timing just never worked out.

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.

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.

And, there's clearly not going to be any outside help coming, anytime soon. These people are going to have to figure out some way to get out of this situation, and they're going to choose all sorts of crazy-ass strategies.

I think that was in the discussions when NBC finally bought it and was trying to figure out how to distinguish it as an event. I'll be honest, we did shoot it with the idea of it being an on-going series, but because I am insane when I get to the end of a season and they give you a big, giant cliff-hanger with no answers, I insisted that we provide all the answers to the questions that we set up, at the beginning.

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'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."
