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."

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.

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.

I feel confident that it will always keep everybody guessing, and yet not in that weird, maddening way where it's like, "Oh, come on, guys!" I think you will be freaked out by the end. I really do. I don't think you'll see it coming at all.

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.
