I just bought Vanishing point on Blu Ray and watched it on my 1080p hi def T.V. and can not believe the quality. The detail is so incredible. You can clearly see the 440 magnum on the hood. I have no ide how they took an old movie and made it so clear. I hope they release Dirty Mary Crazy Larry on Blu Ray.
If they use a digital process, to copy the negatives it's better than a digital original, due to no pixelation, and the software determines the resolution separately for multitude of field depths. (i made that up :thinkerg:BS. the other kind)
