Nice to hear from him after so long, but kind of depressing that nothing is going to come of this.
We don’t actually know this. Lucasfilm/Disney isn’t interested, but after copyright expiration, public-domain outfits like Laserlight may be. They’re always looking to… well… do things on the cheap (even moreso than Lucasfilm), so a pre-made preservation of a previously-unavailable popular classic film would, I’d think, attract quite a lot of interest from them.
Sure, it’d be Mike’s grandkids inking the deal and our grandkids buying the discs (or cranial implants or whatever), but something could still come of Legacy, even if it’s nothing more than a new copy of the film for the Library of Congress (which, frankly, is enough in its own right IMO). It’s always been about the long term goal of preserving history for future generations, not the short-term goal of watching it in our lifetimes. Although I think everyone involved thinks that would have been nice too.
