I was watching my DVD of "Superman: The Movie" today to gear up for "Superman Returns," enjoying the restored print and vintage special effects and it occured to me that even if the original negatives of the Star Wars Trilogy are permanently altered with Special Edition scenes, using the interpositives and separation masters Robert Harris was talking about, in conjunction with the usable scenes from the original negative, would make a full restoration possible. What I was thinking about at the time was the fact that while Superman:The Movie's special effects have been restored and color corrected, they are still the original elements - that's to me what counts the most - so to have the original elements from say, the Hoth Battle, just re-composited without matte lines, is to me anyway, part of the acceptable restoration process. Any thoughts on this one?
