When you start becoming really successful, the demons start to tempt you - the demons of vanity and self importance, drug abuse, the feelings of fraudulence. But, it's also a thrill. That's what I found weird.

How to make a scary movie human, take a movie like Sinister. How can I make that guy so real so that the scary elements of it are more scary and it functions as a genre movie - as the way it's supposed to, you want to hear a ghost story at midnight, that's a good one - but how do you fill it up with humanity inside, in staying true to the genre? You know? Does that make sense?

It was a really strange experience. It was very creative for Alejandro Amenábar. It was almost like it was the most I ever felt like I was helping someone paint. They had a very clear idea of what they wanted it to look like, sound like, be like. So, there was no operating outside the box. The only way to help him was to try to really be a part of his imagination and try to make it happen. He's a super kind and loving person. So, you wanted to help him. It just was none of my normal ways of helping a director work at all. So, it was a unique experience for me that way.

Some people burn out, and some people like Clint Eastwood, he was a wild, international movie star in his 30s, and he's doing the best work of his life now. Go figure.

I think that if you walk through this life and I end up being a bad father, then it won't matter anything else I achieved in my life. It will all be irrelevant.

I was being taken around by a press agent at the Venice Film Festival at age 18. Was it fun? Sure. But it was a dangerous path to be walking on as far as having a substantive life. Because the casualty rate at the Venice Film Festival for 18-year-olds? High.

We're fascinated by things that scare us, and one of the things that scares us is violence. Violence exists. It's a real part of our lives. We are obsessed with what we're scared of, but it certainly doesn't define us.
