In addition to the upcoming Family Guy and Futurama crossover episodes of The Simpsons, Entertainment Weekly reports that there’s also another crossover in the works – a Simpsons/Simpsons one. Set to air on October 19th as this year’s Treehouse of Horror episode, the crossover will be a parody of The Others and follow the Simpsons as they “are haunted by another ghostly family living in the house,” played by the original 1987 version of the Simpsons from The Tracey Ullman Show.
While the Ullman version Simpsons have made a few cameos in recent years, next month’s crossover will be the first to prominently feature them, and the voice cast will “summon their original voices” for the Ullman-era Simpsons too: “People remember Dan’s, but Nancy’s different too,” said executive producer Al Jean. “It was lower-register, and you can see in the difference of this segment. It was really funny to get the interplay [between the two versions of the Simpsons] and for the actors to see the voice evolution. The great thing is we didn’t have to ask – we already had the cast hired for the Tracey Ullman Simpsons.”
