BoJack Horseman is an American adult animated tragicomedy television series created by Raphael Bob-Waksberg. It stars the voices of Will Arnett, Amy Sedaris, Alison Brie, Paul F. Tompkins, and Aaron Paul. Set primarily in Hollywood, the series revolves around the anthropomorphic horse BoJack Horseman (Arnett), a washed-up star of a 1990s sitcom who plans a return to relevance with an autobiography to be written by ghostwriter Diane Nguyen (Brie). It also chronicles his contentions with his agent, Princess Carolyn (Sedaris), former rival Mr. Peanutbutter (Tompkins), roommate Todd Chavez (Paul), and his declining mental health. The series is designed by cartoonist Lisa Hanawalt, a longtime friend to Bob-Waksberg who previously collaborated on the webcomic Tip Me Over, Pour Me Out.
