REPORT-ROTJ-v2.5 - At the screen wipe at 4:57, there appears to be a weird glitch in the audio where it skips (for lack of a better word) momentarily. This appears to be present on all the audio tracks, so it may be native to the film. It’s present on 83 and 93 mixes.
Harmy doesn’t work on audio. But if it’s present in all those mixes, it’s probably real.
