@kk650: First of all, we haven't started to work on this one yet. What I did there was tests because I found those scans.
The plan is to work with that DVNR blu-ray at least for the extended cut, because it's the only source there is. (I think maybe there's an old German DVD release of it too but upscaled it won't look good anyway I guess) The idea is to remove the edge enhancement, add back grain either from the negative scans or the other blu-ray releases to give it the film look back.
We're still open for changing the plans for this project though.
