It's all just rather simple. It's just a collection, not actually incorporated into the movie. The Blu Rays of course are the best source of actual footage, but there is other material I'll be using as well, such as the alternate Han/Leia at Cloud City scene, Declan Mulholland as Jabba scene, the B&W Luke and Treadwell scene (which is a different take than the color version included in the BDs), etc.
Then I realized that there were hundreds of pictures of scenes not even included in the BDs. For instance, when Luke and Vader arrive at the Death Star to face the Emperor:
Or when Luke's mask is removed just before Leia comes to check on his recovery:
I tried to arrange three montages of all the interesting pics I could find together in chronological order with music from the respective films in the background and descriptions every now and then. I could actually call it quits now if I wanted to, as I've got quite a bit and it's already arranged and all, but part of me just doesn't want to finalize it yet because I'm hoping for even more.
In summary, it's just a peek at everything that was missing, first the scenes, then the montages. I'm interested in scenes we already have as well, but from alternate angles or different takes. Or even just brief seconds cut from the films.
Also, using the DVDActive source as a guide, I'm putting stills and clips together of the most notable changes between editions. Yes, this means I will not use most of the very small changes discovered on this site, amazing as they are (though I will probably include 005's albums in the DVD-ROM folder). Just the most obvious will be included. I started this project with my sister in mind and I've been providing her with various editions of the OT and its SEs on DVD, so most of the changes are just noted with pics. But for the PT, where it's not really worth getting a whole new film for just the tiny changes, I've planned on actually showing the clips with their little changes. I don't think I'm going to bother hunting down the ROTS bootleg or rip the BD just for its simple wipe, though. Like I said, only the most notable and obvious changes.
Thanks for all those leads, Silverwook! I'll look through those sites for anything I don't have (or for better quality versions).
Pittrek, there's a very good chance you've got at least something I don't have, and your pictures might be better quality than what I've already got. If you're willing, I'd be very appreciative of you sending me whatever you've got. Thanks for the support, guys :)
