Sleeping Beauty is one of my most desired 4K UHD releases (alongside Bambi, Pinocchio and Fantasia). Need to say that large format goodness on an OLED in 4K with Dolby Vision, grain in tact and original color timing.
Peter Pan and Sword in the Stone as well for me. And Hercules, Tarzan, Atlantis the Lost Empire. Treasure Planet. Only two of those are really classics.
What’s important to realize, is that mostly post-Little Mermaid films were created digitally in 2k format. While 4k might have better colors, any resolution increase is an upscale.
It’s the old hand drawn movies that really need the 4k scans.
