Treehouse of Horror XXVII Details

In an interview with Blastr, Al Jean revealed that the stories in “Treehouse of Horror XXVII” will once again feature guest star voices.

Al Jean teases, “Sarah Silverman plays Lisa’s imaginary friend. When Lisa starts making real friends, the imaginary friend starts murdering them. We also have Drew Carey as a cameo. Donald Fagen of Steely Dan and Kelsey Grammer as Sideshow Bob. Hank Azaria also returns as Frank Grimes, who wasn’t that hard to get,” Al Jean jokes about Hank’s status.

The episode wasn’t originally planned to be the 600th, but in scheduling it happened to become by accident: “We weren’t sure which one was going to be the 600th, so we were just doing aTreehouse show. Our standards for those episodes are very high, and it came out very well. So, at that point, we thought it would be great that the 600th episode would air October 16th so we could make it the Treehouse and it wouldn’t be out of place. Because in the past, I have to admit, we’ve said things like the 302nd episode was really the 300th and tried to fool people, which you cannot do anymore.”

Al Jean adds that they wanted to add three things into it: “One, there’s a special ending which we showed at Comic-Con.”

“There’s also a special beginning, and a third thing we can’t say. But, for the first and the 100th episode, Bart wrote on the chalkboard, ‘I will not celebrate meaningless milestones,’ so we’ve made sure to really celebrate this one.”
