Pete's Dragon (2016) [No 3D Blu-ray, Digital only - SKY UK]

[Interdimensional]

The original isn't considered much of a Disney 'Classic', so they have a reasonable chance of topping it, and seem to be allowed more scope than usual for changing things around.

I don't know why they've apparently discarded some of the more unique elements of the original and changed it into another wild boy in the wilderness story, same year as Tarzan and Jungle Book remakes. We've seen so many 'realistic' CG dragons over the years, that the prospect of seeing another isn't interesting on its own. They'll have to do something creative with it. It doesn't look like they've attempted to emulate the Don Bluth design in any way.
