After Lucas gained all the rights to the original trilogy from fox, i would not be surprised if they handed over the o-negs and let him hack them up for the 1997 special editions, in exchange for the rights to release the prequels.
I hope anything that was cut out into the trim bin was saved.
The color on the Derann films Return of the Jedi is just like i remember seeing the film in 1985, too bad i don't own a copy.
Much too much money for me. They now go for thousands when a few years back you could get a print from Derann for 650 bucks before shipping.
Or roughly half that in British Pounds.
