? let it go ? Disney's megahit "Frozen" may not have become the top grossing film without "Let it go quote. The triple platinum hit inspired tributes and our sing---long. But even before that "Let it go" changed the fate of "Frozen." ? Let it go ? Reporter: The song has become a global phenomenon and inspired a generation of tiny budding singers. ? Let it go let it go ? Reporter: To unleash their inner Elsa. ? I don't care what -- Reporter: But Elsa didn't start out as the misunderstood character? They made her blue and spiky hair and just your quintessential evil queen. She had a coat made out of living weasels. All the weasels would crawl up her and make this living fur coat. Reporter: Once upon a time Elsa was the villain until fate stepped in and the form of songwriters. We were still writing a villain song. And we started getting into the head space of what you'd feel like if you were that isolated. Limit her contact with people and keep her powers hidden from everyone. We knew in this moment she'd go through a transformation from repressed to letting her powers out and sort of trying to get away from society and be who she really was. ? And once we started kind of writing from that -- from the reality of that, we found that we had something to say. So -- We got this hook. Kristin got the hook "Let it go." Because she had to let go of everything she knew and it was this moment of exhilaration when she could finally let go of all she had been holding inside. ? Couldn't keep it in heaven snows I've tried ? And the song wrote itself very quickly. It was a day and a half. ? Well now they know let it go let it go ? And we sent the demo out and everyone went, oh, my gosh much that's great. Shoot, we have to rewrite the whole thing. I don't think they said shoot actually. It was a little more four-letter than that. I went, oh, god. I have to rewrite the entire movie again. Reporter: The song changed the entire plot and movie history was made. ? The cold never bothered me anyway ? So glad they made those changes. And you can catch the story of "Frozen" tonight at:00, 7:00 central right here on ABC.
