You would be surprised. When my brother was a movie theater manager he got invites to a lot of pre-screenings of movies. I was able to go with him a few times and I'll never forget seeing my first movie print before it went through color correction and ADR/sound balancing. Without those steps (and I'm sure others I'm not aware of) the movie experience was very jarring (and somewhat funny).
