I take every opportunity I can to mention Adywan's 'Star Wars Revisited' project. He is an fx guru who was dissatisfied with the Special Editions versions and has gone on to 'improve' them with literally hundreds of minor tweaks, fx improvements, continuity, colour correction, returning to the correct aspect ratio, and of course removing and restoring the worst SE sins such as Greedo shooting.
He's been working for 7 years on Empire Revisited and it is nearly ready for release. It really has been done with a lot of care and attention and the movie has never looked so rich and cinematic. You can download a few minutes from the Revisited Asteroid Chase here...
