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

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.

One of the reasons I don't have kids is because I think people would have been very unfair to them. Think of it. You're still asking me questions about The Exorcist.

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

If you know me, I don't live in this dismal world. I mean, I like to have fun. My friends are comedians.

I was so sad from losing two of my dogs and my mother. I had this vision of all these animals sitting behind bars. They had no control and were scared. That's why I got into fostering and adopting animals out.

If I had children, I would be very selfish. I wouldn't be out doing things. But by not having kids, it makes me freer to travel the world and talk about things I feel are important.
