There are no guest voice actors in this episode. The only speaking parts are given to the five main characters: BoJack, Princess Carolyn, Diane, Mr. Peanutbutter, and Todd.
This is the final episode of the show and the 76th episode overall (not counting the special), completing the show 5 years and 5 months after its first episode.
One of the prisoners that Bojack is practicing his play with is the cartel boss who was holding Todd hostage in BoJack Horseman: The BoJack Horseman Story, Chapter One (2014).
The prison guard bears a striking resemblance to the guard played by Frank Oz in both The Blues Brothers (1980) and Trading Places (1983).
