At that stage, the first major breakthrough was the decision to rewrite the film's protagonist, Anna (who was based on the Gerda character from The Snow Queen), as the younger sibling of Elsa, thereby effectively establishing a family dynamic between the characters.
Prvi veliki korak je bila odluka da Anna u filmu postane protagonist (na temelju lika "Gerda" iz bajke Snježna kraljica), kao mlađa Elzina sestra, čime je uspostavljena obiteljska dinamika između likova.
