I think Treasure Planet would be an amazing Disney live-action remake
I just think about it a lot and want some validation/discussion about other potentially cool remakes Disney could do while they're on their live-action kick.
Not to say the original animation wasn't really excellent as well. But here are my reasons:
The visuals would be completely next-level with current CGI tech. The original animation was gorgeous. Seeing space pirate ships, stunning landscapes and space horizons, and the same kind of choreography remade as live-action would give it that technicolor nearly sensory-overloading Avatar/GOTG quality imo, it wouldn't be made with muted earth-tones like what Lion King has turned out to be and would generally be a very beautiful film if nothing else.
The characters physical appearances don't tend to diverge from humanoid/anthropomorphic characteristics, so not a whole lot of rendering would need to be done on the cast to make them look like the originals; it would allow for a lot of creativity with makeup looks and prosthetics, thus the film would adhere closer to the general definition of 'live-action'
It was a really underrated film but an entertaining one and beautifully made, it'd be a shame not to try and breathe new life in it (and encourage newer audiences to watch/re-watch the original)
Writers could have some more freedom with adapting the plot and adding other elements to it without completely warping it. The characters are already pretty compelling too.
