I've got more info about this release including a conversation with Ben Burtt where he goes into a fair amount of detail about how he originally recorded for Raiders and what he changed for the mix used on the Blu-ray. Dennis Muren was also there talking about the SFX work. I got to see the Raiders in IMAX as well. Unfortunately its all under embargo until later this month . Make sure you have some room on your credit card as this set will come highly recommended. For Indy fans, not only will the film be showing in IMAX, but AMC theaters will be showing all four Indiana Jones films in a marathon screening on September 15th starting at 10:30.
