Season 28 is shaping up to be a big one for The Simpsons; not solely for the series’ first hour-long special, or even the 600th episode, but also some of the familiar faces popping up. To wit, the joint Treehouse of Horror and 600th episode will feature the return of one of Homer’s greatest adversaries, as the famous Frank Grimes pops in from beyond the grave.
The Simpsons still has a few surprises left in its old age, and after going live this past season, Springfield will chart a new frontier: the full hour! After 28 years, America’s favorite family will run a full hour-long episode for the very first time, with special guest Taraji P. Henson and more.
