I'd rather be on this side of the camera. I feel more comfortable. I'd rather keep myself centered and keep my ego as tepid as possible. Because you can get a big head walking around here.

From an early age I loved horror movies. I read books about horror, cops, firemen and military. Over the course of the years I started to see that there's a reality to this. The first movie I was really conscious of seeing was THE EXORCIST and I don't know if any of you have seen that but it scared the sh*t out of me. It really frightened me.

Somebody goes to a soup kitchen and serves the hungry, someone goes to a prison and tries to get people to turn their lives around - those are all Christian charities. This is just another charity the way I look at it. I don't look at it as being special or different.

I happened to write a book about the stuff I've been involved in over the years. It just so happened that my profession is that I was a cop in the New York City Police Department. I guess people thought it was pretty interesting to have these two things meshed together. My life is pretty boring, I don't know why they're doing this. It's fun.

When I learned to build on my faith, the fear pretty much went away. I'm in a dark basement in a home that's demonically infested - that's not my idea of a fun evening, but again it boils down to your faith. That's your protection. That's the only protection we have.

I saw a lot of that. It made me uncomfortable. He's been studying me. We don't just sit down and talk, he's actually studying me. It makes me a little uncomfortable being under that microscope. But I think Eric [Bana] immured himself wight he script and is doing what he needed to do

They [NYPD] tell you how you can act and what you can do your whole entire life. But they always stayed out of it. I did a little here and there for the police department as far as a crime scene that might have occult overtones - they would call me and I'd look into it. But it was usually minor little things.

The NYPD never really had anything to do with it. This is stuff I did on my own time. It just so happened to be that I was a cop for my career. It was my religious belief. The NYPD very wisely stayed away from that. I was grateful that they let me do what I needed to do without getting involved because when you're a cop the NYPD controls you 24/7.
