Right. That's interesting. Can you link me to that Q&A?
Back in 2006/7 he was sticking up for the choice and saying he liked the look of the soft noisy image because the flaws were right for this film.
I remembered where I read his quote about how the movie went from a couple of unrelated scenes to something with an (abstract) overarching structure. It's from Catching the Big Fish.
It used to be here: https://www.youtube.com/watch?v=rDOebdb1BvI but it got taken down. It was a 3 hour conversation between him and a bunch of students from one of his film class things. If I find a re-up I'll post it.
