I have no idea if you would take requests, or if something like this has been done by someone else already, but being a Disney fan, I have a few other Disney movies in mind that, in my opinion, would merit a similar fan restoration effort.
Apart from the before mentioned Cinderella, (that really has been tampered with too much for it's dvd and blu ray release) the first one in line is The Lion King.
The original theatrical version has never been released on dvd or blu ray. Although, in my opinion, it doesn't suffer from major colour/contrast issues like BATB did. Still certain scenes were re-animated for the IMAX release and are present as such on the dvd (crocodiles, waterfalls, SFX removed from the dust cloud) Also the original blue castle logo at the beginning was replaced by the black/golden "special edition" one.
On blu ray, on top of these changes, some rolling clouds are missing in one scene, possibly due to a mistake.
Anyway enough to merit a restoration of the original theatrical version, possibly from the laserdisc.
I am not a technical expert, but because TLK doesn't suffer as much from major colour/contrast issues on dvd and blu ray, would it be possible to only cut and paste the changed scenes into the dvd or blu ray?
Another one that I have been looking for is the so called "work in progress" version of BATB.
This was released on laserdisc and later announced as a viewing option on the platinum dvd. What ended up being on the dvd was actually not the original "work in progress" version, but merely one that jumped back and forth by means of seamless branching between the movie and some pencil animated or story boarded scenes.
Then on blu ray "work in progress" was again a viewing option. This time by means of Picture in Picture, so you watch the movie and see the work in progress on a small screen within the screen.
This time it seems that Disney used the original "work in progress"-print for the PiP.
Is there any way to take the "work in progress" out of the little screen of the Blu Ray? And make it full screen?
