The annual "Treehouse of Horror" episode of The Simpsons has been a series staple since the show's second season, but this year, the series' 28th "Treehouse" episode looks to be a particularly special one for horror aficionados. TVLine reports that William Friedkin, the Academy Award-winning director behind The Exorcist (1973), will lend his voice to "Treehouse of Horror XXVIII."

While there will be an official Exorcist parody in this year's episode, Friedkin will lend his vocal talents elsewhere. Friedkin will take on the role of Dr. Kenneth Humphries in a segment titled "MMM...Homer," which will find the bumbling, perpetually-hungry patriarch cannibalizing himself after running out of food while Marge and the kids are away. Currently, there are no details on what role Friedkin's Dr. Humphries will play in the tale, but the director's participation alone will make the episode worth a look for many fans.

The Simpsons' parody of the The Exorcist, titled "The Exor-sis," will feature the voice of Ben Daniels, who portrays the beleaguered and disgraced priest Father Marcus Keane in Fox's Exorcist TV series. Given that title, it seems Lisa Simpson could have something to do with the sketch, though that is only speculation at this time.

Seeing, or rather hearing, William Friedkin is a rare treat for horror fans and cinephiles, given that the celebrated director is best known for his work on behind the camera on films like The French Connection, which won him an Academy Award for Best Director.

The Simpsons returns for its 29th season October 1st on Fox, while "Treehouse of Horror XXVIII" is set to premiere Sunday, October 22nd.
