That’s awesome! I’ll have to check those things out. The audio changes (especially in Empire) are such a nightmare to keep track of. But those are a few that I’ve never even heard anyone else mention.
I think it would probably be a good idea to put together a streamlined version of my script (without all my dumb jokes), that could be fact-checked and cross-referenced before I get too deep into putting this thing together. I think I should have time to do that within the next couple of days.
4K02 has now released so that would be a great resource to include in your comparison videos. There is also a list of all the changes that have been identified going from 35mm to DVD.
The ESB 70mm print that was scanned a while back can also be found here on the TSWT forums, along with a change list from 70mm to 35mm.
