After directing "The Princess and the Frog", Clements and Musker started working on an adaptation of Terry Pratchett's "Mort", but obtaining the film rights prevented them from continuing with the project. To avoid similar problems, they pitched three new ideas, where by 2011, the two directors started developing the film based on an original idea. In late 2012, the duo announced that they will be directing a new film in the future, but they have their lips sealed for the title, the plot, and the animation style.
