Except in the second last shot - there is a severe loss of detail in the background in the new Blu-ray, almost looks too washed out, what happened there?
Well, it doesn't look like a direct shot, it's a mosaic of shots. There was probably some quality loss in creating the mosaic when the movie was made, so maybe there just isn't any detail to capture for that shot.
Dillon: My men were in that chopper when it got hit! Hopper's orders were to go in and remove grain and the detail just disappeared. Dutch: It didn't disappear. It was scrubbed alive!
