It’s only worth it if ‘we’ found the original camera negative. 4k is almost overkill for release prints.
What I think a lot of people miss is that prints and negatives are very, very different things. The nicest Star Wars prints in existence weren’t worth scanning at more than 4K the day they were struck. A modern, good-quality 35mm negative could theoretically be worth 6K, but with Star Wars we have neither modern, good-quality nor do we have the negative. We have prints, which are great and I’m thankful we do. But in the hierarchy of film restoration sources, prints are trash.
