Charli xcx the Brat Is Over. Meet Charli xcx the Actress.

It’s Friday night at the Sundance Film Festival, and all eyes are on Charli xcx. The hyperpop luminary has claimed the stage of the Eccles, the giant auditorium that serves as the fest’s most spacious venue (and hence where its splashiest selections invariably premiere). Charli is there to introduce The Moment, the sardonic new A24 mockumentary that casts her as a fictionalized, exaggeratedly difficult version of herself. “This movie is about the end of an era,” she tells the tightly packed audience in a brief introduction. And that era, as the movie eventually makes clear, is the one that rocketed the singer to a new level of fame, acclaim, and ubiquity back in the summer of 2024. She’s talking about the defining season of her career, and a bona fide cultural boom with its own font and slime-green palette. Yes, you heard it right, and right from the source: Brat Summer is finally winding down.
