I just watched this wonderful film in the new dolby digital 5.1 mix and it's quite a different experience watching this film with it. I must have seen this film a least 30 times and I have the Mono mix memorized. The new 5.1 mix, while more dynamic, changes the film for me. The background music is different in many scenes and when the narrator introduces each character into their solo quest for the grail, the new 5.1 mix has Michael Palin as the narrator. When listening to it in the original Mono mix the original narrator and music is present. While I don't mind the new 5.1 mix I'm very happy they kept the original mono mix. While I do like 5.1 mixes done to older films, I prefer the original Mono mix in this film. As far as the picture goes it's the best I've ever seen this film look. Could you imagine the world without Monty Python? What a scary thought that is.
