While the debate rages on about how exactly Lightyear fits into Toy Story’s canon, yet another interesting idea is sparked. Has a movie like this, based on an in-universe canon, ever been done before? A story that’s not simply a spin-off following some character, but rather a story that inspires something in the original and expands on the world. Does Pixar's Lightyear mark a new precedent for where Hollywood can begin pulling ideas?
