Towards this goal, if you all find it of use, there's a spreadsheet which lists every shot in the SW films. Feel free to take the spreadsheet and use it as a tool to help keep track of the color correction. Maybe it's easy to drop the color correction settings into a cell/cells of the spreadsheet. This way people could see what's been done and what's still left to do, and at the end will be a complete listing of how to color correct the films.
You_Too if you create a guide, that would be a great way to get other people involved and collaboratively with the spreadsheet, coordination of getting the whole film/s shot by shot corrected might happen a little sooner.
The spreadsheet can be found from this thread:
