Trivia: Originally, Queen Elsa was intended to be the villain of the story. However, when the character's major song, Let it Go, was played for the producers, they concluded that the song was not only very appealing, but its themes of personal empowerment and self-acceptance were too positive for a villain to express. Thus, the story was rewritten to have Elsa as an isolated innocent who is alarmed upon learning that her powers are inadvertently causing harm and struggles to control her powers with Anna's help.
