I though the DVD quality of this classic was not bad till I saw this. As a Blu-ray website review says, the picture has been well cleaned up and the sound improved. What does show up in the greater detail of Blu-ray is the fine grain of the film print. Looking back at my old copy, this seemed to have caused havoc with the DVD encoding. There were odd artefacts, especially on horizontals. This is fixed by this Blu-ray release in a much cleaner, more stable picture. The other bonus is that this disc has decent extras that the DVD does not. I haven't listened to the commentary yet, but the two documentaries are good. The only thing is that the film auto plays and I had to search about on my Panasonic player to find the extras (on a pop-up menu).
