Of course The Exorcist changed my entire life. I don't think there are very many people that will have the experience of sitting in this room, doing a job, and the next thing you know you've been on every television camera around the world, and people are they're frightened of you.

I've lived through what seems to most - and myself - many lives.

Warner Brothers had to hire [a stunt double] and no one thought a child could do this. Billy Friedkin came to me before we were filming [The Exorcist] and said "if you do not do all of this film, the film will be a joke." It's why they stripped the makeup down to the bare minimum, a piece on my chin, piece across my mouth that disfigured my mouth. You have scars here. Take away my eyebrows. It was my real hair. Shampoo was put in it that dried.

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?

I have done, I hope to say I've done things to help make a difference while I'm on this earth. Are animal issues most important to me? Absolutely. I have an affinity with them, but I also care about children and the elderly and always say that the rest of everybody else can fend for themselves because we're in a age where we can. And we're all able to do so.

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.

Its difficult to understand why people don't realize that pets are gifts to mankind
