I feel the need to comment on a few things. In 1997, film restoration was entirely old-school. Digital wasn’t up to the task yet. If you had a 3 color separation and one of the colors shrank at a different rate, they were junk. Fast forward to today and this is the very process that has restored virtually every film. No longer does difference in shrinkage make the 3 color separation useless. It just requires some extra work. In 1989, the Gone With the Wind negatives were found to suffer this in spots, so they had to use a print to patch those places. 20 years later, they used those original negatives in their entirely and realigned them. This has been invaluable with restoring color films shot on color stock. While the original color negative often has faded, some of the colors remain crisper than the color separations. Typically it is the blue/yellow that fades on these negatives and they replace it with the color separation blue/yellow to restore the picture. If the ANH color separations still survive, a complete restoration of it is still possible and relatively easy with modern restoration techniques. Someone who cares just needs to do it.
