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.

People love to talk, so let them have fun talking.

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.

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.

We read about secret lives that people have on the Internet, or alternate lives of a serial killer where the whole family didn't know that their dad or their brother or their child was that. There are all the things in our heart that no one really knows, and I thought that that was interesting territory to explore.

You can't really just think, "Oh, I want to make something that is going to appeal to every single person in the world." You have to just try to make a movie that comes from your heart.

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.
