I think it's good to leave people with the memory of that being a great character. And if we have a reason to bring him back, we'll bring him back.

It's really cool to get these guests on the show BoJack Horseman: not just actors, but, "Can I get Jonathan Lethem on my weird talking horse cartoon show to talk about how growing up in Brooklyn, he always dreamed of being a ringtone?"

We often ask, "Do we have enough humans?" Because it's always fun to come up with an animal in show, but it begins to feel like overkill.

I want each season to feel new and special. I don't want it to feel, "Oh, more of this." That's something that's easy to do in the first three seasons, and harder to do as you go. I'd rather err on the side of blowing up everything and being like, "Why did you do that? There was more story to tell there," and moving the family to Mexico like on Weeds, instead of people going, "Oh, we've seen this already. We're tired of this."

I don't know if that's the best story for BoJack, long-term. I do love the world, and I love playing around in it and it feels like an elastic enough world that, any story I want to tell, I can tell about these characters in this world. I can talk about parents and children, husbands and wives, the troops, or Hollywood. It does feel like an endless playground at this point, it would be a shame if we cut it off early for fear of repeating the same things over and over again. But I am looking to move the story and character somewhat.

'Lost in Translation' movie says something interesting about the alienation of being a stranger in a strange land, but also of being a celebrity. That kind of feeling of not being in the same strata as everyone else.

Jessica Biel is a really interesting case. She actually called us after the table read and said, "You guys should go meaner." She pitched us, and said, "Look, I know there are a lot of things to make fun of me about. I don't want people to think you're pulling punches. Please, dive in." We asked, "Could we tell a joke about your friend and mentor Stephen Collins?" And she said, "Well maybe not so much in that area. As long as the jokes were about me, I'm game for everything."
