No extras are needed with this, maybe some trailers, since I'll just use it as a third disc with my USA 2-Disc Blu-ray release I own. Great you're keeping the film grain Andrea, hate it when preservationists and fan editors remove it with DVNR and EE. Will you be ripping the English DTS-MA 5.1 bit-for-bit or what? Just throw in a ton of subtitles if need be.
Obviously the current Blu-ray is great except for the needed color correction which you're doing. Keeping it AVC will be perfect.
