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."

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?"

I am wary of repeating myself too much. In this age of Netflix, as a Netflix show, if you want to go back and watch a season 1 episode, you can do that easily. I'm not interested in repeating the same story beats over and over and over again. But part of the truth of BoJack story is about how much he repeats himself and these patterns that are difficult to get out of. I'm trying not to be evasive about that. I'm not using that as an excuse. I think that's convenient to fall back on as a TV writer: "Oh, it's a show about stagnation."

I think you can imagine everyone has ankle weights on, or technology, and there's a reason that people aren't floating around. But I also liked this idea that in this world, people forgot they can swim. The modern world weighs you down, there's always emails to check, you've gotta go to your job and pay your mortgage. You're not really thinking, "Oh, yeah, I can swim around." BoJack discovering it is a big deal, and kind of fun.

It was fun figuring out the science of the world as much as we wanted to figure out, and then playing fast and loose in other places. Which we do with our show in general. One of the things we love about the BoJack Horseman show is that we can always fall back on, "It's a ridiculous cartoon." And it is! It's a serious, relationship-based grounded character tragedy, but it is also a ridiculous cartoon.

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.
