Haaland - who hails from Norway - stars as Natch in ViQueens, a family animated adventure-comedy that follows fearless Vikings Ingrid and Hedvig on their expedition from Norway to China.
Norwegian director Harald Zwart, 60, told The Hollywood Reporter: "As a Norwegian storyteller making a Viking adventure for a global audience, having Erling Haaland join ViQueens feels incredibly exciting.
"Erling has already become a kind of real-life Viking icon around the world - powerful, fearless, and uniquely Norwegian. Bringing him into this universe as himself gives the film an unexpected energy and authenticity that felt completely right for this story."
Solveig Langeland, managing director of Sola Media, said: "Erling Haaland transcends sports - he's a global cultural figure.
"His involvement brings another exciting dimension to a film that already combines international adventure, humour, and emotional storytelling in a way we believe will resonate with audiences everywhere."
ViQueens will see Haaland, 25, join a star-studded cast, including pop singer Rita Ora and actor Ella Purnell, who voice lead characters Hedvig and Ingrid respectively.
ViQueens is due to launch in Norway on Christmas Day.
