The Simpsons are entering their thirties!

This upcoming season marks their thirtieth season and conveniently enough it begins on Sunday September 30.

Creator Matt Groening, actress Tress MacNeille (Skinner’s mother, Crazy Cat Lady, Lunchlady Doris, Dolph the bully and heaps of incidental characters) and producers Al Jean and David Silverman all appeared on this year’s panel, letting us in on some of their favourite guest stars, freeze frame gags, lines and episodes (tellingly, the latter were all early ones).

After a small clip from last season featuring Homer eating, well, everything in New Orleans for a few minutes (and then needing one of the city’s famous vomitoriums), Silverman explained that computer compositing allows the family to travel to more “artistic settings,” which frees up the writers.

When asked about guests, Anne Hathaway, who did all her own singing during her appearance on the show, was cited as a panel-favorite guest star. This year guests will include: Gal Gadot, Emily Deschanel, Jon Lovitz, JK Simmons and Guillermo Del Toro.

The panel also showcased a new teaser poster for this year’s “Treehouse of Horror” special, one which looks to be geared towards spoofing movies like Jurassic World and Invasion of the Body Snatchers. You can see more of that here.

Jean also teased that one of the new season’s opening couch gags will lampoon fellow animated sitcom Bob’s Burgers.

When asked how they would ideally end the show Jean said he would want to go back to the Christmas pageant from the first episode. He quickly followed this saying “but now that I’ve said it, it probably won’t happen.”

Jean would later confirm that he was pretty sure 30 would not be the end for The Simpsons.
