I think the other post above is referring to the version of a Toy Story sequel that was in production down in Burbank at Disney in the early 2000's (after TS2 came out). That production was shut down when Disney and Pixar merged in the mid 2000's.
scrapped - after we got this version of the film back, we decided to rewrite the story. that meant that we substantially rebuild the film in the next year, even after we had recovered the version from Galyn's machine.
That’s certainly possible. But if folks on this site don’t know how ToyStory or JurassicPark were rendered back in the day, let alone like almost every movie with CG in it since, that would be a little surprising. But maybe?
