 Eric Pierpoint resumed his role as Pawnee Police Chief Hugh Trumple, a character he previously played in the earlier third season episode "Ron & Tammy: Part Two". "Eagleton" features a cameo appearance by Mike Scully, a writer and producer on the Fox Broadcasting Company animated comedy series The Simpsons, as a speakers at the Pawnee public forum who suggests the building of a second fence around the Eagleton fence. Scully has worked as a screenwriter and consulting producer on Parks and Recreation since the first season. He did not originally wish to take the part and only agreed to it reluctantly. Originally, he only had one line, but improvised additional dialogue after Amy Poehler asked him why he believed a second fence should be built.
