Gladiator uncut would also be a big draw for myself personally.
I think the newly found outtakes from ghostbusters will show up at some point.
But how about The Good the Bad the Ugly. There is a glimmer of hope that these things can be put right and if 4K HDR put’s them Right I think adoption of that format will be good.
Rogue One original cut before re-shoots would be another one for the list.
Braveheart uncut also.
Highlander extended cut.
