From Kristen Bell to Josh Gad, some iconic voice actors are reprising their roles in the Frozen 3 cast. The first Frozen movie saw a character named Anna set out on a mission to find her missing sister, Queen Elsa, after she ran away from home after accidentally freezing and dooming her kingdom to an eternal winter. While on this journey, Anna also meets several complex characters, such as Olaf and Kristoff, who all teach her some valuable life lessons along the way. After the characters proved to be a hit with the audience, they soon returned in 2019 for Frozen II, which now explored the origins of Elsa's powers.
