All the ways 'Wicked: For Good' differs from the Broadway musical

• "Wicked: For Good" officially opens in theaters Friday, Nov. 21.
• The second half of the Broadway musical has been expanded for the movie screen, meaning there are significant plot differences.
• Surprise! "Wicked" Part 2 adds two new songs for Elphaba and Glinda to sing.

Spoiler alert! We're discussing major plot details about the movie musical “Wicked: For Good." Stop reading now if you haven't seen it yet and don't want to know.

There have always been two types of “Wicked” fans.

On one side, there are those who worship the stage show’s whimsical first act, which has all the most memorable songs and Shiz University shenanigans. And then there’s the other camp that goes to bat for Act 2, a darker yet goofier affair that attempts to shoehorn every “Wizard of Oz” character and reference into just under an hour.

Let us rejoicify, then, that the musical’s second act finally has some breathing room in “Wicked: For Good” (in theaters now), which meaningfully expands the story into a relatively brisk 2 hours and 17 minutes.

“There was a lot of freedom this time around to get in there and go deeper,” says director Jon M. Chu, who was eager to up the emotional ante for witches Elphaba (Cynthia Erivo) and Glinda (Ariana Grande), but also flesh out the supporting characters.

Here are some of the most significant differences between the Broadway musical and the new movie:

'Wicked: For Good' has two new songs – and a mega-mix?

The witches of Oz are each given emotional new numbers, written by original "Wicked" composer Stephen Schwartz: “No Place Like Home,” Elphaba’s plea to the animals to stay and fight the tyrannical Wizard (Jeff Goldblum), and “The Girl in the Bubble,” Glinda’s operatic reflection on her own complicity and sheltered existence as an adulated public figure.

But the film also begins by remixing three of the first movie's most beloved songs: Elphaba’s hopeful “The Wizard and I” is now about bidding “the Wizard goodbye.” “What Is This Feeling?” has new lyrics sung by Glinda’s “obsessulated” royal court. And “Popular” is chanted by Emerald City guards at a celebration for Glinda.

Wheelchair user Nessarose (Marissa Bode) no longer walks in the ‘Wicked’ movie

In the stage show, Elphaba casts a spell that gives her sister, Nessa, who uses a wheelchair, the ability to walk. But fans have long argued that the plot point is ableist, and screenwriters Winnie Holzman and Dana Fox tweaked the movie sequence to make Nessa fly instead.

“I was so happy with the change, the old narrative was outdated,” Bode recently told Go Magazine. The actress has been paralyzed from the waist down since age 11, and opened doors as the first wheelchair user cast as Nessa in the musical’s 22-year history.

Glinda (Ariana Grande) has a less-than-magical childhood backstory

In the first movie, Elphaba reconnects with her girlhood self and finds the courage to stick her neck out. “Wicked: For Good” gives Glinda a similar treatment, thanks in part to a flashback scene set at a children's birthday party. Young Glinda (Scarlett Spears) tries to impress her friends by pretending that she created a rainbow through magic. But privately, she bemoans the fact that she has no real powers of her own.

The sequence unlocks Glinda as a vulnerable character, revealing her insecurities and why she always longed to be seen as special like Elphaba, who was born with mystical abilities.

‘Wonderful’ isn't just a duet with the Wizard (Jeff Goldblum)

In the musical, Elphaba sneaks into the Emerald City to try and free the flying monkeys, only for the Wizard to discover her. Through the jaunty song “Wonderful,” he explains how he came to Oz and tries to convince Elphaba to join his side, saying how people need a leader to believe in, even if it’s all built on lies.

But the movie makes the Wizard’s offer harder to resist by bringing Glinda into the number. She attempts to sway Elphaba by telling her that she'll no longer be a wanted woman if she chooses to work alongside the Wizard. Glinda even invokes a verse of “Defying Gravity,” telling Elphaba: “Think of what we could do together.”

A ton of animals crash Glinda’s wedding to Fiyero (Jonathan Bailey)

On stage, Fiyero escapes the Emerald City with Elphaba immediately after she threatens to keep fighting the Wizard. But the movie raises the stakes by having Elphaba free dozens of animals from their cages, unleashing a stampede that storms through Glinda’s wedding ceremony.

The change gives Glinda a clearer motive when she decides to betray Elphaba to the Wizard and Madame Morrible (Michelle Yeoh): Not only did her best friend run off with her man, but her perfect nuptials ended in total destruction. It also makes “I’m Not That Girl (Reprise)” even more heartbreaking, as Glinda tearfully sings among the wreckage.

Elphaba (Cynthia Erivo) no longer screams ‘Fiyero!’ before ‘No Good Deed’

As any “Wicked” diehard will tell you, one of the stage show’s most-quoted lines happens immediately after Fiyero is captured by the Wizard’s guards and left to die in a cornfield, having just spent a passionate night in Elphaba’s hideout.

Filled with rage that she couldn’t save her lover, Elphaba shrieks Fiyero’s name in agony, drawing out the final vowel before launching into the vengeful power ballad “No Good Deed.” But in the movie, it’s only Glinda who yells his name as she tries to stop his arrest.

The Cowardly Lion (voiced by Colman Domingo) actually talks in the film

“Wicked” shows how Fiyero became the Scarecrow and Boq (Ethan Slater) turned into the Tin Man, but it also explains why the Cowardly Lion is such a scaredy cat.

When he was just a cub, Elphaba saved him from a classroom demonstration and set him free in the woods. But as we learn in the song “March of the Witch Hunters,” the Cowardly Lion grew to resent Elphaba for not letting him “fight his own battles when he was young.”

On stage, the Tin Man speaks on behalf of the lion, who is almost entirely hidden from view, save for his tail. But in the movie, the Cowardly Lion is given a few lines of dialogue early in the film, as he warns the other animals that they shouldn’t trust Elphaba.
