I can go back to my very first movie, Thirteen, and think about that exact moment when I saw Nikki Reed and Evan Rachel Wood do their chemistry read audition together. It just came alive. I was filming it with a video camera and I was like, "I know I can make a good movie now."

I like doing commentary. As a filmmaker and film student, I think it's really interesting to hear what a director did and how they figured out how to do things. I often like the technical commentaries myself.

Even after I had just done Twilight, which made $400 million at the worldwide box office, I could not get financing for three or four projects that I really loved and I thought people would love because they didn't fit some studio or investor's model of thinking, "This will definitely make money." It's a business and a film does potentially cost millions of dollars, and they have to think that they're going to get their money back somehow.

I thought it would be quite a challenge to direct a mystery thriller. I hadn't really done something like that.

I worked for 20 directors as a production designer, most male. I was on the set to witness firsthand a range of sometimes atrocious emotions - well-documented firings, yellings, fights between directors and actors, hookers, abusive things, budget overages, lack of preparation. A man gets a standing ovation for crying because he's so sensitive, but a woman is shamed.

I was told 50 percent of the population gets cancer. Everybody is going to be affected.

As a director, you've got to have quite a few projects going because you never know which one will actually come together with the financing and get the green light.
