Well i’d say that puts ROTJ out in front for the time being.
I was looking at tv show called pearl that used footage from tora! tora! tora! Doubt it is deleted footage though? Honestly still yet to see the film but I will soon.
I will update the list in a bit cheers SilverWook:)
I suppose the mother of all re-used footage films is battle beyond the stars / Space raiders / starquest 2 / Dead Space and I am sure it also had another release for those special effects shots. But it’s not deleted scenes…
