Again, the fact that Mike has the original version preserved more than makes up for any qualms I might have about what is being done for Legacy. Even with George no longer in control, I am still highly skeptical that Lucasfilm would ever do such a loving scan of whatever surviving interpositive or whatever they might still have of the original version.
I read from someone on Blu-ray.com that ILM's composites generally had blue stars, that they were purposely filtering the starfield element. But this person was referring to their mid-80s stuff (Jedi, Star Trek III, and so on). Dunno if it was true for the original. ILM's techniques did change as the years went on.
