Kristen: It was 2011 and Chris Buck came to New York and pitched us - we had just come off of "Winnie the Pooh, "which we had worked with Peter Del Vecho, the producer, so he saw that we really enjoyed being part of the storytelling as well as the songwriting. So he pulled us in. Chris Buck came and he showed us this visual development picture of two girls - young girls. One was throwing snow up into the air and the other, younger sister, was looking at her like she was this superhero and it really resonated with our own experience cause we have two daughters. We have an eight year old and a four year old.
Kristen: And we’re married, yes, I should say. And, just how the younger thinks that the older one is such a superhero and all of that entire dynamic and as it runs through sisterhood.
