The featurette on the laserdisc is very poor and doesn’t explain the changes well at all. As far as making of or behind the scenes material goes its poor as hell. I think Anatomy of a Dewback is better. I don’t have the Cinefex or American cinematographer special edition material, or ILM Into the Digital realm.
An in depth look at the Special Edition and the why probably never will happen, as it was rushed and sloppily done to r&d the prequel. And somehow George got Fox to pay for it with the excuse of the 20th Anniversary of Star Wars.
On the featurette McCallum says if we don’t do this, we will never have the film to release again, but isn’t that what happened with the original being lost. They didn’t restore the movie its left in an unrestored state even now. The Special Edition isn’t the film.
