I know there are film versions available....it's a matter of money really. This is why it probably won't happen any time soon. Believe you me, if I could afford it I'd be buying the prints so they could get scanned. I would do the same for the 1997 SE in the same circumstance.
I still can't figure out if the LD for TPM is cropped like the DVD or not cropped like the theatrical release and the Blu-ray. It's so confusing sometimes....LOL.
