American Graffiti was also broadcast in Europe for the first time a while back in HD, but good luck finding it anyware on the net. Also HDNET released it in 1080i.
The original non lowry, non cgi raiders is also out there somewhere in HD.
The version of graffiti is the lowry cleanup and added cgi shot one though.
The betterlooking copy of Raiders is also cleaned up by lowry but has an additional cgi shot.
THX 1138 should not have any dvnr applied to it. It was shot documentary style and in techiscope and is supposed to have a heavy amount of grain. American Graffiti is also supposed to have that look.
The indiana jones films also were supposed to have a fine amount of grain. It was desided by Douglas Slocombe the cinematographer, Spielberg and Lucas. Supposed to remind us of the old movie serials.
Star Wars on the other hand while shot like lucas wanted as documentary camera style, was designed to have less grain than those other pictures and finer detail in the visuals which is why they used the vistavision process for the optical plates. Also the film was shot with a fairy tale, fantasy look. Brighter colors and warmer tones than Lucas other movies. Supposed to be expensive Hollywood type pictures shot on soundstages. The Hollywood LUCAS immerged on star wars, although he makes his films outside of hollywood because he thinks he is an independant completely. Although without Fox funding Star Wars it would have never been made.
Though the videogame coloring appeared with the Phantom Menace. The same oversaturated and blown out palette was Used on Attack of the Clones, Revenge of the Sith, and Indiana Jones KOTCS.
Too bad they ruined phantom menace and crystal skull. 2 movies completely shot on film that were altered in post production to look like they were shot with HD Video. Although perhaps the digital intermediate process is also at fault here. No longer actually physically editing the film on a kem or movieola and on a digital avid machine. Also the 2k not as good as the actual film. and then reprinting back to film removes the quality of the image. IF the digital intermediate was more like 4k maybe the ruination would not happen?
Well at least the grain structure on indy IV was not destroyed to make the film look more clean.
That was done on Episode 1 for the dvd release.
