this is if you have the digital video masters all ready to go.
it does not take into account digital restoration, color correction, additional effects or fixes costs, as well as the elements being transfered from film. Supposedly fox put up the twenty plus million dollars to restore the special editions from scratch starting with the original negative, and of course most of that restoration was done by hand along with the re-comps of original opticals being done with modern computer technology as well as the final digital scanning.
YCM Labs did the restoration.
then it was further restored by Lowry in 0'4, take in the cost to also restored the sound elements and dialogue tracks the sky is the limit on how much they actually spent. If it is that expensive may be why he is reluctant to spend his own money on restoring the oot. On top of that the original negative was altered. that is the best source for a restoration, being a first generation or no generation copy of the film coming right from the camera. that is what they used to restore the bond films by lowry the o-neg. sure Lucas must still have the interpositives or selected takes of those scenes on film rolls but the quality is at least 1 to 2 generations older than the o-neg.
