Season 33 of The Simpsons to kick off with "most musical episode we’ve ever done"

The Simpsons will be kicking off their 33rd season in a big way this September, announcing that the premiere will be "the most musical episode" they've ever done.

Frozen megastar Kristen Bell is set to guest star (as Marge's singing voice) on the episode entitled The Star Of The Backstage, with producers revealing that it'll have all original songs. Of course, The Simpsons are no strangers to a sing-song, and have even had many huge rock and metal classics featured, but this is set to be the first-ever all-musical episode.

“The premiere this year is the most musical episode we’ve ever done – almost wall-to-wall music,” producer Matt Selman tells Variety. “It’s like a Broadway musical of an episode, with all original songs, and we’ve got Kristen Bell playing the role of Marge’s singing voice. We all love Marge’s voice, but this is the singing voice that’s different, let’s just say.”

The Star Of The Backstage will air on September 26. Watch Comic-Con panel The Simpsons Season 33 And Beyond below for even more info about what else is to come:
