When filming the long-anticipated movie adaptation of Wicked, director Jon M. Chu knew the production would eventually reach a moment that could define the entire project: the iconic performance of the song “Defying Gravity.” The number has long been the emotional centerpiece of the stage musical, and recreating its soaring impact for cinema required both enormous technical precision and extraordinary vocal power.
For Chu, the stakes felt enormous. The film, produced on a massive budget reportedly around $145 million, involved elaborate sets, complex mechanical rigs, and hundreds of crew members working simultaneously to bring the world of Oz to life. But one creative choice made the moment even more daunting. Instead of relying solely on pre-recorded studio vocals—a standard method in many large musical films—Chu insisted that the song be performed live during filming.
That decision placed immense pressure on the film’s star, Cynthia Erivo, who portrays Elphaba. The scene required her not only to deliver one of the most demanding vocal performances in musical theater, but to do so while suspended high above the set on a complicated mechanical rig designed to simulate flight.
As cameras rolled, the massive set fell silent. Around 200 crew members watched from behind lights, cranes, and monitors while Erivo was slowly lifted into the air. Harnessed to the rig and surrounded by towering set pieces, she prepared to deliver the song’s climactic notes—moments that Broadway audiences have waited for decades to hear.
According to Chu, what happened next stunned everyone present.
Rather than holding back to preserve her voice during the physically challenging scene, Erivo reportedly leaned fully into the performance. As the rig lifted her higher above the set, she projected the song’s signature lines with extraordinary force. Her voice echoed through the soundstage as she pushed through the emotional crescendo of the number, delivering the famous climactic belt that defines “Defying Gravity.”
Chu later admitted that the power of the moment overwhelmed him. Sitting behind the monitors, he watched the performance unfold and realized that the raw emotion and intensity were unlike anything he had expected during filming. For a brief moment, he even forgot to call “cut.”
Around him, the normally busy film crew stood completely still. Technicians, camera operators, and assistants—people accustomed to the chaos of large-scale productions—were reportedly frozen in silence as the final notes rang through the studio. The scene had transcended its technical complexity and turned into something closer to a live theatrical moment.
Part of what made the performance so striking was the physical intensity involved. Suspended in the harness, Erivo leaned into the rig while sustaining powerful notes, her entire body engaged in the performance. The combination of height, movement, and vocal power created an image that captured the emotional core of Elphaba’s transformation: a woman embracing her strength while defying the forces trying to hold her down.
For Chu, the moment became one of the most memorable experiences of the entire production. Directing large musical numbers often requires precise choreography and countless technical adjustments, but this particular take felt different. The authenticity of a live vocal performance gave the scene a raw emotional quality that could not easily be replicated in a studio recording.
Long before audiences see the finished film, that moment on set has already become legendary among the cast and crew. In a production defined by massive sets, elaborate effects, and meticulous planning, it was a single voice—powerful, fearless, and soaring—that briefly stopped an entire soundstage in stunned silence.
