Here is a beautiful french animated film by Benoît Philippon and Alexandre Heboyan.

Now with the help of a wax-child named Glim and the warrior, Sohone who also became the Sun Guardian, they go out on an exciting journey to get the Sun back and restore the Moon to their rightful place in the sky.”
