Collins is the only star attached to the “Polly Pocket” film so far. Back in 2021, she celebrated the film in an Instagram post, writing, “Little Lil, big news. As a child who was obsessed with Polly Pockets, it’s a real dream come true to announce this project! I am partnering with the most inspiring powerhouse team — Robbie Brenner, @lenadunham, @mattel and @mgmstudios — to reintroduce Polly to the world in a fun, modern way… bringing these tiny toys to the big screen. Truly so excited to be coming on as both a producer and Polly herself! Can’t wait to dive into this pastel world…” She shared a photo of herself as a child inside a Polly Pocket toy.
