I'm cutting anything from the special edition restoration onward out of the equation. I mean, there's what, several hundred differences between the SE and the OOT? Has any professional studio actually reconstructed an earlier version of one of their films in such a way instead of simply transferring an older print/IP? Whenever I talk about "those interpositives" I mean the most recently struck pre-SE IP, but for all I know that could be more than twenty years old at this point and beyond any hope of restoration. Going the route of private collectors (as suggested by Bill Hunt) and getting Criterion to spearhead it (as suggested by Jay) might be the only real option available.
