The Supernova Voice That Made Grown Directors Weep

While the production faced its fair share of internet commentary, critics and crew members consistently agreed that Zegler's actual vocal performance on set was utterly spellbinding. During her initial screen tests, she performed a rendition of “Waiting on a Wish” that reportedly made the room weep, cementing her as a "shining supernova" in the eyes of the creators. On set, her crystal-clear singing voice was so powerful that it routinely elevated the entire mood of the crew, turning stressful, heavy CGI shooting days into joyful, impromptu Broadway-level concerts.
