Tools used for the animation are pencil, charcoal, and digital colouring.
Animation is by Michael Dudok de Wit and Arjan Wilschut. The film has no dialog. As the Dutch landscapes live through their seasons, so the girl lives through hers. She becomes a young woman, has a family, and in time she becomes old, yet within her there is always a deep longing for her father. Michael Dudok de Wit grew up and went to school in Holland.
