Case in point: A movie based on Polly Pocket starring Lily Collins is in the works amid Barbie's box office dominance. And according to Robbie Brenner, the head of Mattel Films and a producer on Barbie and all developing Mattel movie projects, there's already a "great" script written by Lena Dunham for the live-action adaptation of the beloved miniature toy. "First of all, they are two of my favourite ladies ever," Brenner told Variety in an interview. "It's been an amazing collaboration." She continued, "Lena is so collaborative. She's incredible. Lily is so smart and so specific. It's just been an incredible collaboration, so we are thrilled about it." News of a Polly Pocket movie first broke in 2021, when Collins was named as its lead star. "As a child who was obsessed with Polly Pockets, it's a real dream come true to announce this project!" the Emily in Paris actress wrote on Instagram at the time. "Truly so excited to be coming on as both a producer and Polly herself! Can't wait to dive into this pastel world."
