He's a professional in this field, and apparently he has access to a fantastic source. He's mainly restoring the original Star Wars trilogy, but I think he's also making a few very subtle adjustments here and there to stabilize ship movement in some of the space combat and so on. But it's 99% straight restoration/preservation. And he has the skills to do it.

LeeThorogood: I don't think "want" has anything to do with it, he's simply worried about getting in trouble if he made it publicly available. If he could, I'm sure he'd be happy to. He's a big Star Wars fan. :)

zombie, how do you like those starfields in that shot?! :)
