There was originally a different ending to Disney's 'Frozen' and its finally being revealed why the ending was changed.
Producer Peter Del Vecho talks about the transition of the characters:
“So when we started off, Anna and Elsa were not sisters. They weren’t even royal. So Anna was not a princess. Elsa was a self-proclaimed Snow Queen, but she was a villain and pure evil."
“The problem was that we felt like we had seen it before,” Del Vecho says. “It wasn’t satisfying. We had no emotional connection to Elsa — we didn’t care about her because she had spent the whole movie being the villain. We weren’t drawn in. The characters weren’t relatable.”
“One of the things Chris Buck had in most versions of the film was a moment where Anna’s heart was frozen and needed to be thawed. Chris said, ‘Does it always need to be true love’s kiss that solves that problem? Does it always have to be the man who comes in and rescues the female? Could it be something different?’ and that led to a different ending. Now that they’re related, Elsa had her own fear and it was Anna who would save the day instead of Elsa by rescuing her sister — and it would be that selfless act that thawed Elsa’s heart."
