I didn't have a clue. I grew up Protestant in Connecticut at the Saugatuck Congregational Church. We didn't talk about the devil. That's Catholicism. And so, that was my safety net. And I always say, it's probably a good thing they didn't hire a Catholic child, who may have heard about the devil, the things that were in the closet. And no one wanted to discuss them.

I can't answer for my mother. She was a very private person, and did not discuss a lot of things.

While you're in the moment of anything that's confusing in your life, you're in the moment, and you have to figure it out. You can go up or down. And I just kept working on the higher road, and trying. I got very involved with medication.

For me reading the book [The Exorcist], I had the same questions that everyone else had. How does she jump up and down off the bed? How does her head spin around? How does she throw up?

Look what they did to MaCauley Culkin. The poor child. I know because I've been there. But I could say after living my life, truth will always win out. And no one can take my character away from me anymore.

We didn't talk about devil on the set. My mother and I didn't talk about it. Billy Friedkin and I didn't talk about it. It was a closet subject. But it was the best thing that happened because I had no idea what I was going.

Kids shouldn't see all the violence they do these days. But the industry just doesn't care.
