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?

Modeling was pretty difficult back then. I did not find the business something that I had an interest in. I wanted to be a veterinarian.

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.

The animals are right here, right in front of us. And how we treat these companions is a test.

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 have been a vegetarian for about 10 years. And it really was due to the reading that I did. And they explain so that you understand why it's important for the planet's survival along with compassion for animals. It certainly made it much easier for me. I lost weight really fast. My mother died from cancer so this is all very personal to me. And I just would like the planet to be a better place. And I think you'll find a vegetarian diet to be really incredible these days

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