In the annotated screenplays it's said none of Brackett's draft was left. Not a bit of it. Lucas put her name there as a tribute

Yeah I remember that, but I seem to remember producer Julia Phillips talking about this (and we're talking many years ago) and she was praising Brackett for what she did on that script given that she was also sick. Hm, now I'm confused.

But anyway, I don't really care who wrote it, I just know it's the best written of all six Star Wars movies, and the best directed.
