Academy Award-winning Swedish actress Alicia Vikander is set to lead the voice cast of upcoming stop-motion animation film Moomins and the Winter Wonderland, set for global release in December.

“Growing up, Moomins was my favorite childhood book, and now I can be part of the Moomins family,” Vikander said in a statement. “I’ll be playing both the roles of Little My and Sorry-oo. I am so excited to be part of the Moomins feature Moomins and the Winter Wonderland.”

Stellan Skarsgard also has joined the cast as the voice of Moominpapa and will executive produce.

The Moomins were created by the Finnish writer Tove Jansson in a series of books and comic strips, originally published in Swedish in the 1940s. The iconic fairy tale characters — a carefree family of white, roundish creatures with large snouts that make them resemble lovable hippopotamuses — are a staple of kids culture around the world, thanks to translations of the original books and comic strips, along with television and film adaptations, and even a theme park called Moomin World in Naantali, Finland.

Finish film company Filmkompaniet and Polish animation studio Animoon are co-producing the new project. Los Angeles-based production, distribution and IP management company Global Genesis Group is handling international distribution and sales.

Based on Jansson’s original books, with a screenplay from Małgorzata Więckowicz-Zyla, Piotr Szczepanowicz and Ira Carpelan, Moomins and the Winter Wonderland will be created from existing, vintage footage from original stop-motion Moomins productions co-produced by Jupiter Film and Film Polski in the 1980s.
