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.

Even during the casting process, the pools of talent are so deep when you have a call for Latin women or black women or a middle-aged woman because they never get their shot. There's so much talent there.

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.

I think it would be exhausting and depressing, to write, to watch and to live, if it was just focused on drama. It's heavy. Also, I think the humor really highlights the pathos and the struggle. You can slam it up against drama, and it makes both shine.

On the other hand, we worked a year on this and some people are going to watch it in a night and go, "We want more!" And there is something I miss about the longing and the anticipation for the next episode.

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.

If you go to a network and say, "I wanna do prison stories about black women and Latino women and old women," you're not gonna make a sale. But, if you've got this blonde girl going to prison, you can get in there, and then you can tell all the stories. I just thought it was a terrific gateway drug into all the things I wanted to get into.
