I just read the rumour (hopefully untrue!) on TFN that Lucas has made the following alteration to the soon to be released blu ray of Return of the Jedi:
Darth Vader yells "Noooo" as Luke is being electrocuted with Force Lightning by the Emperor.
If this is true, I think he has crossed the line and actually ruined his movies. I hated a lot of other changes, but this would be right up there and probably my most hated change.
The reason I post this here is it drives home the importance of this project. With Dark Jedi's work we will have two versions in high definition: the real theatrical versions that we all love, and the bastardized GL editions, which have some good changes but a whole bunch of bad ones. It just makes this project all the more important.
