Disney's animated movie Frozen almost saw one of its most popular songs not make the final cut. Loosely adapted from the fairytale by Hans Christian Andersen, Frozen tells the story of sisters, Anna and Elsa, Princesses of Arendelle, who are separated by their parents when Elsa loses control of her ice powers; when Elsa accidentally reveals her powers at her coronation and turns summer into winter, Anna must find her sister and put things right. Frozen was released to critical and commercial acclaim, becoming one of the highest-grossing films in history, grossing more than $1.2 billion worldwide, and receiving praise for its characters and screenplay.
