The voice cast includes Will Arnett as BoJack Horseman, Aaron Paul as Todd Chavez, Amy Sedaris as Princess Carolyn, Alison Brie as Diane Nguyen and Paul F. Tompkins as Mr. Peanutbutter.
The third season follows BoJack trying to get an Oscar for his film “Secretariat,” and along the way takes him to even darker depths than last season provided. Given how ambiguous the ending of the third season is — no spoilers, but there is a bombshell dropped in just the last few minutes — from a plot perspective, this fourth season practically had to happen.
“BoJack Horseman” is created and executive produced by Raphael Bob-Waksberg. Steven A. Cohen and Noel Bright executive produce along with Arnett and Paul. The series was designed by graphic artist Lisa Hanawalt and animated by LA-based ShadowMachine. The show is a Tornante Production from Michael Eisner’s The Tornante Company.
