She may be small (micro-sized, to be exact), but Polly Pocket is heading to the big screen.

Mattel Films‘ latest project is a Polly Pocket live-action movie, inspired by the micro-doll line of the same name. The company will work with Metro Goldwyn Mayer (MGM), Lena Dunham’s production company Good Thing Going, and Lily Collins on the project.

Dunham (“Industry,” “Girls”) will also write and direct the family comedy with Collins (“Emily in Paris,” “MANK”) starring in the leading role as Polly. The film follows a young girl and a pocket-sized woman who form a friendship.

“Polly Pocket was responsible for countless hours of childhood escapism for me — Polly gave me a tiny world of magic and autonomy to narrate, so it’s pretty poetic to be tackling these same ideas now as a director collaborating with the brilliant Lily Collins, Robbie Brenner, Mattel, and MGM. I’m so thrilled to bring to bear both my love of this historic property and also my deep-seated belief that young women need smart playful films that speak to them without condescension,” Dunham says.

Robbie Brenner and Kevin McKeon will lead the project for Mattel Films. Sandino Moya-Smith and Winnie Carrillo will lead for MGM. Good Thing Going’s Liz Watson and Michael P. Cohen will serve as executive producers.

“I’m so excited to partner with this inspiring powerhouse of a team. Developing this project with Robbie, Lena, Mattel and MGM to reintroduce Polly in a fun, modern way has been such a treat. As a child who was obsessed with Polly Pocket, this is a real dream come true and I can’t wait to bring these tiny toys to the big screen,” Collins says.

Polly Pocket was first introduced more than 30 years ago. Mattel reintroduced the brand for a new generation of kids in 2018 with a product line that pays homage to the brand’s origins. Kids can also watch Polly and her adventures in an animated series on Netflix and YouTube.

“Polly Pocket is an iconic franchise that has resonated with children for more than three decades.” says Brenner, executive producer of Mattel Films. “The incredible nostalgia that Polly evokes, coupled with Lena’s fresh approach and Lily’s take on the character, will introduce an entirely new interpretation of this classic brand to audiences. We look forward to working with MGM to produce a feature film that will appeal to the whole family.”

Polly Pocket joins other Mattel Films projects in development including movies based on American Girl, Barbie, Barney, Hot Wheels, Magic 8 Ball, Major Matt Mason, Masters of the Universe, Rock ‘Em Sock ‘Em Robots, Thomas & Friends, UNO, View Master, and Wishbone.
