The oppression of it, the sense of helplessness, and really being part of a system and a bureaucracy that is arbitrary. I never thought of the depth of losing your freedom and what that meant. And I was surprised and delighted by ways people maintain their humanity and try to survive.

You want everyone to be a full character. No one is just evil, or very few people are, hopefully. They're characters, so you want to flush them out. You've got to show all sides of them. There is definitely an antagonistic relationship between guards and prisoners, and I do think it flares up.

I'm always looking for those places where you can slam really disparate people up against one another, and they have to deal with each other. There are very few crossroads anymore. We talk about this country as this big melting pot, but it's a mosaic. There's all these pieces, they're next to each other, they're not necessarily mixing. And I'm looking for those spaces where people actually do mix.

We watched these auditions and could only pick one. Sometimes we would add new characters 'cause we wanted to use another actress. There were so many people who were just waiting for something like this.

But, how many times can you get exactly what you want, when you want it? Not very often. So, why not have it with entertainment? That's what it's fun. It's fun! I find that's how I'm watching, more and more. My kids go on binges, and I get sucked in. And then, it's the middle of the night and they're late for school, the next day.

I begged her to write a song and she said yes. I am a huge Regina Spektor fan. I think she's a genius and just a lovely soul, and I wanted her voice on it. And she agreed, which is just the coolest thing, ever. She knocked it out of the park.

Piper reads the scripts, and we email a lot. Most of her comments are on the more technical side, like "This wouldn't happen. This is against the rules." She's been extremely respectful of our taking her story, and then veering left with it and taking it in its own direction. But, I always want her involved because she's the mother of all this.
