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.

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."

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.

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.

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.

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.'"
