Hal, as for my Episode III changes... let's see, it's been a while. I remember cutting a lot of what I thought were silly lines during the opening battle. I removed the business in the elevator on Grievous's ship completely. The scene with Palpatine and Windu after the crash landing is removed. All the scenes between Anakin and Padme are shortened, but two in particular were removed. The balcony scene and the one where he accuses her of sounding like a separatist. There were things I liked in the latter, but overall I thought things worked better once it was gone.
Mostly it's a lot of little stuff. I didn't do nearly as much to Episode III as I did the first two. My main beef was that I felt like it took too long to get going, so most of my changes are in the first half. I did remove the part from the Anakin/Kenobi duel where Anakin says "from my point of view the Jedi are evil!" as it seemed like thematic notes from the script margins somehow got mistaken as dialogue... it's just too pedantic. And lines like "only my new powers can save you" had to go, in my estimation. Ugh.
All three of my edits are somewhat conservative, in that they don't try and fundamentally change or re-order the story. But I wanted to attempt a more complete "de-awkwardization" than I'd seen attempted in other versions.
Again, thanks for the taking the time to check these out, folks.
