I was obviously talking about the white speckles. I don't see anything else that matches the word "dust" on this frame.
Universal is definitely not dealing with different prints. They scanned an interpositive back in 2002 and didn't scan shit since. It costs money to transfer a whole film so no, I didn't think about that because it's stupid.
The dusts are not on the original negative or the interpositive because they are not the same on the previous analog releases.
