I believe Fast Times at Ridgemont High had some changes as well. Some home video releases had different songs due to licensing but I think this was resolved by the time the film made it to DVD. The surround mix first introduced on the 2005 DVD had some minor effects changes I believe. That DVD as well as the BD does not have the mono. The original DVD and the High School Reunion DVD as far as I know has the correct original mono!
It’s me Pete 1972! You remember when we commented on the Jaws videos? Looks like another film is getting the audio revisionism treatment. According to Digital Bits and some fans, Batman 89’s Dolby Atmos mix has a lot of changes with the sound effects. Gun shots have been altered and the starting up of the Batmobile is changed too. Also Digital Bits said that the Dolby 5.1 on the 4K is a downmix and not the 5.1 that was on the previous Blu Ray.
