The Shadow King was fleshed out as an idea to be made fully in stop motion by Henry Selick. There were lots of artists who brought the main characters to life in animation tests. Storyboards were created, set designs sketched out, voice acting recorded - and negotiations with Travis Knight and Disney to see what could be done. Laika studios had to pull the plug due to financing and other issues. It is one of those projects that could have been great, if only fate didn't have its way.
