I recently visited the website of the german DVD-label "Edition Filmmuseum", who restore and release a large number of lost films from the vaults of filmmuseums. And in their "soon to come"-section, this struck my eyes:
The Unknown Orson Welles 1965-1985

Now, having done a quick look around, I got that that is the title of what is more or less a public showing of reels that various vaults acquired (as most of you know). But considering these official showings only included small amounts of footage of each "unmade"/"lost" film, I wonder what the DVD is comprised of. A documentary? Various shorts and a large amount of raw workprint material?
Either way, I hope somebody knows something about this or can research further. I am intrigued.
