During a recent late-night Wikipedia dive, I was surprised to learn that Charli XCX — fresh off the massive recognition of “Brat” — has not one, not two, not three but seven appearances in films set to be released in the near future. These upcoming projects include fantasy film “100 Nights of Hero” and erotic thriller “I Want Your Sex” from queer icon Gregg Araki. She’ll also appear in “The Gallerist,” which features the likes of Natalie Portman and Jenna Ortega.
