Inside Out co-writer Meg LeFauve and Nathan Greno (Tangled) were directing the project, while Frozen songwriters Robert Lopez and Kirsten Anderson-Lopez were to have written songs for the film.

But according to the studio, creative walls were being hit.

"It's impossible to know when we begin a project how the creative process will unfold, and sometimes, no matter how much we love an idea or how much heart goes into it, we find that it just isn’t working," said Walt Disney and Pixar Animation Studios president Ed Catmull. "With Gigantic, we've come to that point, and although it's a difficult decision, we are ending active development for now. We are focusing our energies on another project that has been in the works, which we'll be sharing more about soon, now set for Thanksgiving 2020."

Details regarding the new project were not revealed, although insiders said it would be an original feature.

Animation is known for its long development process and it is not uncommon for projects to be put on the shelf or to morph from one concept to another. It is also not the first time Disney Animation or its sister company Pixar have taken projects off the schedule either to further work on them or shelve them indefinitely. King of the Elves and Newt were titles that had been actively in the works in the last decade that are now inactive.

Disney Animation next has Ralph Breaks the Internet: Wreck-It Ralph 2, which is set to open Nov. 21, 2018, and Frozen 2, which is slated to bow Nov. 27, 2019.
