Friend of mine says the R1 cinematographer mentions seeing a 4K DCP of ANH in this interview:
I have a theory about this: we see some of the pilots from ANH with footage taken straight from the original film. Was a restoration finalized to service this purpose? Or just generally for the cinematographer to get a feel for how the era is supposed to look?
Somewhere was an article where Gareth stated that they found reels and reels of un digitized film from ANH. These shots where all on those reels. (Original Negatives even!)
For how well and how quickly they cleaned those up, it gives you real hope that someone somewhere will find an intact negative and do right by it.
