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

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.

According to my religious belief, I'm sorry if you feel like I'm pushing this on you - my religious belief is that you behave the way God wants us to behave. And that's simply love God and love one another. If we did that, there would be no need for any of the other commandments. It would be great. But in the same vein, we would have obtained paradise by that point. And it's tougher to get to paradise by that point.

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.

There is a correlation between evil. There is a primary evil that comes directly from the Devil. Even though all evil stems from the Devil, the Devil sometimes interacts with people in the physical world and the spiritual world and sometimes there's just plain evil that people do to one another. And I've seen plenty of that over the course of 20 years.

Well, actually I look at the book and the movie [Deliver Us From Evil] - the movie isn't about a cop or the Devil, it's about God. There's a spirituality. We have aspects of life we're involved in but we really have no idea about the spiritual battle that rages around us that we are the subject of. The whole matter is the Devil tries to take souls away from God, and God tries to keep them. And that's what this is all about.

There's an element of realism to it. I immersed myself more in the subject as a young adult. Then I started to get involved with a lot of people that were involved in it, and they would just bring me along basically. And I learned and decided that my Christian charity, what I wanted to do to serve God's will, was to help people that were ensnared by the demonic.
