1. The first thing that is seen is a black and white, vintage version of the Universal emblem, which is the same as the one that was used in 1939.
The year when The Wizard of Oz was released. Like in The Wizard of Oz, the screen likewise alternates between black and white and color.
2. The title card for Wicked is printed similarly to that of The Wizard of Oz.
3. In the opening scene, we see the Scarecrow, Tin Man, Dorothy, and the Cowardly Lion as the camera moves over Oz. Later, more on the Fab Four!
4. In addition, 9 million vibrant tulips are planted in Oz’s fields in a rainbow pattern, which is obviously an homage to Judy Garland’s well-known song “Somewhere Over the Rainbow.”
Fun fact: Because Jon insisted on avoiding visual effects whenever feasible, the Wicked team really planted all nine million tulips in real life. Crazy!
5. A group of Munchkinland youngsters are seen ringing bells and performing the well-known song from.
The Wizard of Oz, “Ding Dong!” as they commemorate the death of the Wicked Witch of the West. The witch has passed away.
6. The introductory tune, “No One Mourns the Wicked,” has subtle references to the Wizard of Oz instrumental “Miss Gulch” and “Somewhere Over the Rainbow.”
7. Throughout the movie, hot air balloons appear often, alluding to The Wizard’s well-known use of them for travel.
In the last moments, Glinda (Ariana Grande) and Elphaba (Cynthia Erivo) utilize the balloons, which are branded across Emerald City, to convey invitations to see The Wizard.
8. During Glinda and Elphaba’s moments of connection, like as in “No One Mourns the Wicked,” “Dancing Through Life,”
“Popular,” and “Defying Gravity,” the song “For Good,” which plays while they consider their relationship, is softly played throughout the movie.
9. British stage actress Alice Fearn, who portrayed Elphaba in the West End production of Wicked, plays Glinda’s mother.
10. Elphaba nods to the removal of talking animals in Oz, which becomes a major story element, when she first uses her magic abilities at Shiz University by levating.
A seat that strikes a mural of the Wizard, forcing it to collapse and exposing one of the animal professors behind it.
11. Glinda makes an apparent reference to Dorothy’s famous ruby shoes from The Wizard of Oz when she wears a pair of red heels during “Popular.”
Like Dorothy, Glinda even clicks her heels three times! Additionally, their father presents Nessarose, Elphaba’s sister, with a pair of silver shoes in a ruby red case, the same color as Dorothy’s in the original L. Frank Baum novel.
12. A tornado is also shown on Nessarose’s shoes, referring to the storm that drops Dorothy in Oz. Additionally, throughout the movie.
Nessa dons striped socks, a nod to the outfit she wore in the well-known scene in The Wizard of Oz while she is under the house.
13. In “Dancing Through Life,” Fiyero (played by Jonathan Bailey) dances around corn insignias, hinting at his ultimate metamorphosis into the Scarecrow.
14. Everyone else is sent to sleep by Elphaba’s magic spell, but Fiyero is the only one who is not affected.
The Wicked Witch of the West’s spell to induce slumber has no effect on the Scarecrow in The Wizard of Oz.
15. The destiny of Boq (Ethan Slater) as the Tin Man is also hinted at. He finally loses his heart in Part 2.
As shown by the fact that Glinda puts his red handkerchief in the pocket near his heart after rejecting him.
(Boq also states that he cries “a lot,” which is a very significant detail once he transforms into the Tin Man.)
The baby lion cub, who later turns into the Cowardly Lion in The Wizard of Oz, is saved by Elphaba and Fiyero.
Elphaba rides a bike while carrying the cub in the basket, evoking the human equivalent of the original Wizard of Oz Wicked Witch, Almira Gulch, who rides off with Dorothy’s pet, Toto.
