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.

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.

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.

People always joke that 'dog' spells 'god' backwards. They should consider that it might be the higher power coming down to see just how well they do, what kind of people they are. The animals are right here, right in front of us. And how we treat these companions is a test.

There was a golden retriever who saved countless lives on September 11 by going back in to find people. His companion was in a wheelchair. He got him out and kept going back in to save others.
