If there’s any interest in a preservation, I have both the Signature and 1995 letterbox LDs and can capture the raw PCM mixes. I also have the rare 2 hour cut of THE SHARK IS STILL WORKING, which was recently released on the Blu-ray, but was cut down by Universal and rescored due to licensing issues. I think a definitive JAWS Blu-ray could be made with the resources on this site.
The original was 3+ hours.
Are you sure you have the original?
