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 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 you're working on a television show with actors, what you hope you're doing is playing jazz with them all the time.

It's not unheard of, in the course of life, that if there's enough interest in it, we could consider going a second season or doing another chapter. I keep looking at it as books in a series, and this season is the first book.
