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.

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.

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?

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.

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.

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.
