I'll have to watch again to pick out some favorites, but there is one possible missed moment that does come to mind. When Han is climbing onto the kangaroo-chicken-jackalope, or whatever it is, to go out a search for Luke, we get one of the worst line reads of the entire movie: "Your tauntaun will freeze before you reach the first marker!" And they let it slide right past. Should have got a chuckle at least, I would think.
