Layers are not difficult for me. You have the luxury of takes, so if you feel like, say, you did not take in the fact that your aunt is across the way in one take, you do it again and try to add that piece.
An Oscar means a lot of things because it's like the ultimate award for a filmmaker so it feels great. But I think you have to consider awards with some distance and not get obsessed with it. When you're creating you shouldn't think about it.
I would certainly say that films like Time Code and the Loss of Sexual Innocence were far more rewarding to me in terms of being able to move forward as a filmmaker.
