For the first hour-long special in its 28-season history, The Simpsons is bringing in a cast of all-stars.
Taraji P. Henson, RZA, Common, Snoop Dogg, and Keegan-Michael Key will all voice characters in the episode, an epic Great Gatsby/hip-hop mashup titled The Great Phatsby.
According to The Root, the show will follow Mr. Burns as he tries to get revenge on a music producer who scammed him. Burns will be joined by rapper-turned-fancy candle salesman Jazzy James (Key) and the producer's ex-wife, Praline (Henson), the Simpson-ized doppleganger of Taraji's Cookie Lyon on Empire.
"This, I think now, is the pinnacle of my career," Key told Rolling Stone. "I'm done, because I just did The Simpsons."
Simpsons stand-bys Homer and Bart will come along for the ride, too, along with Snoop Dogg, Common, and RZA, who will reportedly guest-voice as themselves.
Tune in this Sunday, January 15 on FOX to catch the episode.
