I've probably mentioned this before, but Derann did release BATB, Aladdin, and several other classics complete on Super 8. Whether they are in their original aspect ratios, I have no idea.
On a side note, does anyone know how many workprints are out there? (Aside from BATB Work in Progress.) I had at least one back in the 90's, but it was on the tail end of a bootleg tape of The Black Cauldron and incomplete as a result.
