I'm in the camp that agrees that this is purely Criterion material. If you've seen their excellent 3-disc set for Brazil... it has the entire 90-minute (note: 40 minutes shorter than Gilliam's director's cut) hack-job cut with a commentary noting all the changes. Also, Criterion is releasing a 3-disc set for Mr. Arkadin/Confidential Report (Orson Welles). Welles was taken out of the editing room, resulting in him never getting to finish the film his way. As a result, Criterion's set has the released version, a later re-cut by Corinth Films, and a new historian's comprehensive cut that is an estimate of Welles's intended cut.

They could put both Arabian Knight and The Princess and the Cobbler on one disc (72/80 minutes respectively - only 152 minutes). If a restoration happens, that would be the main star on the first disc. Another disc could have the workprint. All four versions in 2.35:1 anamorphic widescreen, too. As for extras, as seen with what has been found... there's the Thames documentary, the camera tests, maybe A Christmas Carol (who owns it), the storyboards (in still frame format), the best of RWS commercials, etc. No telling what stuff is out there in collections.

Criterion has even said they're interested in doing something animated, but nothing has really come to their attention... after all, most stuff is already being handled by studios well. They already have ties with Buena Vista (they've handled some Hollywood/Touchstone/Miramax films), they've done multiple cuts, they've included commercials (Kagemusha has Kurosawa's Suntory commercials), and even exclusive restorations (Spartacus).
