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.

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 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 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.

And then, what I hope will happen at the end is that there will be a big enough springboard that, if we chose to go for a second season, we would have one. But, there will be none of those maddening teases that we're going to tell you the answers and then we don't tell you the answers. That gave NBC the idea of making it a mini-series.

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.

Only in Southern California do camping grounds actually have wifi, so I was sitting in my tent and I started reading it on my computer, and I couldn't put it down. More importantly, I kept getting up in the middle of the night going, "Oh, this is cool," so I pitched them an idea that they seemed to like.
