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.

Sometimes, a scene goes on too long and, with this being a suspense story and murder mystery that you're trying to discover through her heightened paranoia, you don't want scenes that take you on a tangent. Sometimes, you love those scenes, but you know that it's better not to be in the overall film. So, I'm not sad that they're not in the main movie, but I do think it's fun for people to get to watch them, if they want to.

When I talk to film students, I always say, "Buy the DVDs and listen to the commentaries, look at the making of, look at the behind-the-scenes," because that's such a great learning tool.

For Twilight, I wasn't thinking it was going to be a crazy success, or anything. It had been rejected by all the major studios. Nobody wanted to make it and they didn't think it would make any money, but I read the book and I thought, "Wow, I want to capture that feeling of just being crazy in love. I wonder if I can do that in a film." That was my challenge.

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."

It's interesting for me to do the commentary with the actors because, as a director, you're so in your own world that you see it from your perspective, your issues and what you were trying to do, and then it's really very fun to hear their perspective on how it was to do a particular scene or how they felt, and sometimes, I didn't even know that, at the time.
