There is a sound that seems to come from BB-8 in the scene Ryan-SWI noted (from a different cam version). To me it sounds like a squeak from BB-8, or possibly a mistake with the sound of a TIE Fighter blaster shot that occurs a second or two later? - but there is definitely a noise there that’s not present in the other cam version and early bluray rip from last week.
Should be interesting when we all get our hands on the official release bluray/dvd/digital downloads…
