IFC has a short Q&A with Natalie about Black Swan, but there are a couple interesting questions in there. The whole article is here and below are the questions that stood out for me.

What was the best piece of advice you received that applied to the making of this film?

Include the camera.

What was the toughest thing to overcome, whether it applies to a particular scene or the film as a whole?

Shooting late at night. Our days were so long that we often found ourselves at 4:00AM shooting crucial scenes or on Pointe. That was tough.

What’s your favorite thing about your film that’s been largely uncommented upon?

The music by Clint Mansell is masterful and totally sets the tone and pace for the film.

What’s been your favorite film, book or album from the past year?

My favorite films have been “Tiny Furniture,” “The Kids are Alright” and “Please Give.” My favorite books have been [Nicole Krauss’] “Great House,” [Jonathan Franzen’s] “Freedom” and [Patti Smith’s] “Just Kids.”
