regarding NP being difficult, I forget which films it was. I know there was an extra on the set of Ep2 who said she was kind of a primadonna. I don't know if any of it is true, I'd say its likely that if it is it has a lot to do with GLs directing (or lack there of). NP was great in cold mountain, I've only seen her in SW for so long that I forgot she could act.
