I just stumbled upon Mike Verta’s livestream from May 2020 about his unreleased 4K restoration. I remember him working on this a number of years ago, when he was about to present it to Fox and Disney. In this livestream he gives some new info about it. Pretty interesting stuff! I wish Disney would just release his restoration. It looks phenomenal!
