Thanks!

Just for curiosity, do you know some websites that list all the portions which added or converted by Mr. Lukas over the course of years?

By the way, I am always annoyed by the strange computer graphics creatures added in the scene of Mos Eisley. Actually, I was not particularly impressed by the spongy figures in the original version either. Mr. Lukas enhanced them and added some, which made me dislike them even more. What it was that the designs of the creatures or aliens lack of science and there is no systematic concept behind. Even burgess shale fossils have a particular taste in their outlook. So it wasn't a visual quality matter...

Yes, I meant Luke informs Leia not Leia informs Luke:) I agree with you on the third category. I think George Lukas is one of the best movie creators who's name remain in the history. But some of his later works utilize and ruin his old/original works, such as Indiana Jones and the Kingdom of the Crystal Skull. I was really shocked (in a negative way) when I saw this movie.
