The movie was one of my favourites as a kid, watching it in a late (for my age) night TV show plastered with commercials, in an old black and white TV set. It just gripped me all the same, I still remember how the thrill was slowly but steadily growing inside me as the movie went on. I still think that the pace of the movie is just superb. Now, for the transfer: the best I have seen in a very long time. I never thought a film from the 60' could look this sharp, contrasted, natural...it is just gorgeus. Mind that the original celluloid grains are there, but I just happen to love them, they add more to the purely cinematic experience. There isn't the slightest sign of compression; no DNR has been used, yet the image is extremely detailed, thus showing how artificial looking such digital manipulation is. The sound has been largely improved, with a good spatial distribution and clarity, even bass sounds, for a film this old. If you like this movie, don't hesitate an instant, just go for the blu-ray. You can give the DVD away, you will never want to watch it after the blu-ray.
