Anna of Arendelle is the spirited protagonist of Disney's Frozen (2013) and Frozen 2 (2019), voiced as an adult by Kristen Bell, with child actors like Livvy Stubenrauch providing her younger voice. As the younger sister of Queen Elsa, she embarks on a dangerous adventure to bring her sister back after Elsa accidentally plunges their kingdom into an eternal winter. Loosely based on Gerda from Hans Christian Andersen's "The Snow Queen," the character was notoriously difficult to adapt, with attempts dating back to Walt Disney in 1943 failing because the original story lacked direct conflict between Gerda and the Snow Queen. The project was finally revived after the success of Tangled (announced December 22, 2011), when directors Chris Buck and Jennifer Lee solved the problem by reimagining the characters as sisters, creating a dynamic relationship that satisfied producer John Lasseter. Critics praised Anna's determination and enthusiasm, as well as Kristen Bell's performance, making her a beloved addition to the Disney princess lineup.
