But what about lines that are never said? I always assumed there was a script on hand from preproduction because sometimes there are captions for things that never actually get said, or words at the start of a sentence as the audio fades in, or really quiet whispers or background dialogue from extras that wasn't even meant to be discernible but somehow is heard and captioned.

Yeah it's not all the time, but I do notice it. We watch everything with subtitles because my wife is deaf in one ear and misses things if there are accents, fast talking, etc. I actually have found it enhances my own viewing too. I never realized how many little things I missed or misheard. I'm glad people like you exist!
