Wicked — Easter Eggs & Hidden Details

Before a single frame of Oz appears, the Universal globe spins in vintage black and white — the studio dug out a period logo so the film could open the way movies did in 1939, the year MGM's The Wizard of Oz premiered. Color floods in only once Oz takes over, echoing that film's famous sepia-to-Technicolor switch, and the title card that follows is lettered in the same ornate style as the 1939 main titles. It's a mission statement before the story even starts: this Oz remembers the old one.

Wicked opens minutes after The Wizard of Oz ends. As the camera sweeps across Oz toward Munchkinland during 'No One Mourns the Wicked,' you can pick out Dorothy, Toto, the Scarecrow, the Tin Man and the Lion far below, trudging down the Yellow Brick Road with the Witch's confiscated broomstick in tow — a rainbow hanging in the sky for good measure. Blink and the entire 1939 cast is gone, but the timeline stamp is deliberate: Glinda's bubble arrives to announce a death Dorothy just caused.

When Munchkinland erupts over news of the Witch's death, children ring bells and bang pots in patterns that echo 'Ding Dong! The Witch Is Dead,' and rhythmic fragments of the 1939 song are stitched into the number's percussion. It's one of several spots where the score smuggles in Harold Arlen's melodies — 'Over the Rainbow' itself drifts through the soundtrack as the camera crosses Munchkinland's rainbow-striped tulip fields. The movie can't sing the old songs outright, so it hums them under its breath.

Those endless flower fields around Munchkinland are not CGI. Production designer Nathan Crowley — backed by Jon M. Chu's everything-on-camera mandate — worked with Norfolk farmer Mark Eves to grow roughly nine million real tulips, planted in bands that shift from blues through whites to reds and oranges. Read from the air, the beds form a rainbow: a living tribute to Judy Garland's 'Over the Rainbow.' Crowley was pressured to fake it with visual effects and refused; after the shoot, the bulbs went back into farm rotation for future seasons.

The Wicked Witch of the West never had a name until Gregory Maguire's 1995 novel built one out of her creator's byline: say L. Frank Baum's initials — L, F, B — out loud and you get 'El-pha-ba.' The film inherits the tribute wholesale, which means every classmate sneering 'Elphaba' through the halls of Shiz is unknowingly invoking the man who invented Oz in 1900. It's the deepest-rooted easter egg in the entire franchise, hiding inside the protagonist's own name.

Scan the establishing shots of Shiz University and you'll find the Clock of the Time Dragon — the mechanical, smoke-breathing dragon that looms over the proscenium at every stage performance of Wicked. It originates in Gregory Maguire's novel as a traveling oracle-theater, and the Broadway design implies the whole show unfolds inside the clock's pageant. Its film appearance is a pure handshake to theatre and book fans: the storyteller's machine is still on the premises, even when nobody points a spotlight at it.

Listen closely in the early Shiz scenes and the dialogue name-drops two deep-cut villains. 'Miss Gulch' is Almira Gulch, the bicycle-riding Kansas neighbor who doubles as the Witch in The Wizard of Oz's frame story — a character who technically shouldn't exist inside Oz at all. 'Professor Mombi' is the child-stealing witch from Baum's 1904 sequel The Marvelous Land of Oz. Neither name gets an explanation, which is exactly what makes the drops so satisfying for people who know the source material.

Every time Elphaba sings the word 'Unlimited' — first in 'The Wizard and I,' climactically in 'Defying Gravity' — she's singing the first seven notes of 'Over the Rainbow' in rhythmic disguise. Composer Stephen Schwartz has confirmed the tribute for years, noting the altered rhythm keeps it an homage rather than a quotation, and has said he tucked Wizard of Oz passages into the score in multiple places. The film's orchestrations keep the motif fully intact, so Judy Garland's anthem quietly haunts Elphaba's biggest moments of hope.

'What Is This Feeling?' relocates Elphaba and Glinda's mutual loathing to a physical-education class where the roommates spar with staffs — choreography that deliberately previews the wand-versus-broomstick brawl the two witches have in the story's second act. On stage that scuffle erupts in Act II; on film, the gym class is a promise that Wicked: For Good keeps. Watch their footwork here and you're watching the rematch being blocked out a whole movie early.

The Ozdust Ballroom's house piano is pecked at by ornamental fancy chickens, and that is not random whimsy: before L. Frank Baum wrote The Wonderful Wizard of Oz, he bred and exhibited prize show poultry. Director Jon M. Chu confirmed the birds are a deliberate tribute to Baum's pre-Oz life, part of a broader effort to fold the author's real biography and the original book illustrations into the film's design language. It might be the single most obscure confirmed egg in the movie — invisible without a crew interview.

Mid-makeover in 'Popular,' Glinda produces a pair of glittering ruby-red heels and clicks them together — Dorothy's signature there's-no-place-like-home move — before the shoes are set aside among her other options. It's a cheeky wink at the most famous footwear in film history, which this Oz pointedly can't hand to anyone: the ruby slippers were MGM's Technicolor-era invention, so Wicked keeps its actual magic shoes book-accurate silver and lets Glinda's closet do the referencing instead.

'One Short Day' pauses for Wiz-O-Mania, an Emerald City stage spectacular fronted by two 'Wise Ones' — played by Idina Menzel and Kristin Chenoweth, who originated Elphaba and Glinda on Broadway in 2003. Their newly written verse recounts how the Grimmerie came to Oz, Menzel uncorks her signature 'Defying Gravity' riff, and Chenoweth playfully clamps a hand over Ariana Grande's mouth mid-note — a jab at the rivalry the press once invented between the originals. Composer Stephen Schwartz framed the sequence as one big easter egg, and Cynthia Erivo described Menzel adjusting her witch's hat as 'the passing of the broom.'

The people who built the musical are hiding inside its Emerald City. Composer-lyricist Stephen Schwartz plays the palace guard who peers through the door and grants Elphaba and Glinda their audience with the Wizard, while Winnie Holzman, who wrote the show's book, appears among the city crowds during 'One Short Day.' Broadway alumni are scattered nearby too: original-cast Fiyero Michael McCorry Rose fronts the Wiz-O-Mania show, and West End Elphaba Alice Fearn appears earlier in the film as Glinda's mother.

Jon M. Chu built an escalating technology timeline into the staging and confirmed it while promoting the home release: the film moves from characters 'crawling on the floor in the beginning' to horseback, boats, bicycles, a train, and finally flight, as Elphaba takes to the sky on her broom. Chu describes it as an allegory about progress — The Wizard of Oz was written as an American fairytale, and transportation is how America transformed itself, for better and worse, just like the Wizard's industrialized Oz. Choreographer Christopher Scott adds that even the students' book-slaps and shoulder raises at Shiz encode meaning.
