I doubt the “LOST CUT” will ever get an official release. A version produced by STAR WARS fans would be great.
It’ll never be 100% accurate but there is enough deleted/alternate material out there to construct a rough approximation.
That is exactly my hope with this edit. It’s a shame that more has not yet been provided, but at the same time, I’m pretty grateful for what we have and what we can do with it.
