Winslet narrates this family drama, which is written and directed by Luc Jacquet. A little girl sees a fox on her way home from school and is fascinated enough to track and befriend the fox over the years. Jacquet on casting Winslet:
It was very important for me, that the film wasn’t just narrated, but it was actually inhabited. She had to find the right tone, which would lead her into her childhood and discover some very deep emotions, while at the same time without overloading. She went straight into the character, brought her own warmth and I found her fascinating.
