I mixed Silverscreen edition with your 2/7 version on the Dark Vader shot and I thought it was an alright result
Whilst not anything revolutionary this was simply blended using a luma key on BLack to help blend out the black crush. Looks like a bit of warping on the left going on though.
I did the smae with the dianoga shot where it pops out of the water (Black Crush again( but it’s not so simple due to the smearing in the silverscreen edition.
