The Phantom Menace was shot on 35MM so that can be true 4K, however the other two prequels were shot digitally and not even at 1080p
So by trying to appear technologically innovative Lucas shot AotC and RotS on formats that can’t meet today’s high resolution standards, but the first one from 1977 can? That’s hilarious.
AotC and RotS are the worst two IMO anyway.
You can’t deny he was technologically innovative though, since most movies today are shot in digital cameras and Lucas was the one that started the trend.
