Twenty years ago, the Broadway-shaking musical 'Wicked' opened its doors in New York City — and the theatre world was never the same.

Based on Gregory Maguire's book Wicked: The Life And Times Of The Wicked Witch Of The West — itself influenced by L. Frank Baum's The Wonderful Wizard Of Oz — the musical debuted on Broadway on Oct. 30, 2003, six months after it premiered in San Francisco, California on May 28.\

Two years later, the musical was honored by the world's leading society of music people; it won the golden gramophone for Best Musical Theatre Album at the 2005 GRAMMYs.\

Fifteen years and numberless inspired performances after its premiere, Ariana Grande, Ledisi and Adam Lambert as well as GRAMMY winners Pentatonix performed with original cast members Idina Menzel and Kristin Chenoweth to celebrate 'Wicked,' in a performance dubbed the "Wicked 15 Anniversary Concert."

Also back in 2018, the play about the green witch named Elphaba also garnered a special called A Very Wicked Halloween, starring the aforementioned musical luminaries.

"The themes of the show, the love and friendship aspects," "Wicked" star Kristin Chenoweth told the San Francisco Chronicle at the time. "We can look at these two characters looking forward to seeing everything."

For Mitch Grassi from Pentatonix, it was a full-circle moment for him to perform in the special. "It's a full circle moment, we grew up with this show and the [album] kind of shaped us as performers," Grassi told Playbill.

'Wicked' is still on Broadway — and is about to be on the silver screen! On Nov. 27, 2024, Cynthia Erivo and Grande will star in Wicked: Part One, a film adaptation of the play. (The sequel, Part Two, is scheduled to release on Nov. 26, 2025.)

And on the stage proper, the team behind 'Wicked' is plotting a special anniversary show at the Gershwin Theatre — and on Oct. 30, the anniversary proper, the Empire State Building will light up green in commemoration of the show.

On Halloween, the New York Public Library will hold a free panel discussion about the musical, featuring panelists in book writer Winnie Holzman, producer David Stone and composer and lyricist Stephen Schwartz.

And after spooky season concludes, traveling iterations of the show will continue to roll on throughout the world — with a home base in London providing the (slightly altered) experience for Wicked fans in the United Kingdom.

Whether or not you're able to catch the film, these celebration shows, or just a good old performance, keep a little wickedness in your heart in tribute this Halloween!
