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.

We end up producing the opposite of what we intended, and turn our children into unpopular, isolated adults.

What we have to remember is that children matter as much as adults, but they aren't equal with adults

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.

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.

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.

People need to understand; I may have been very innocent. Didn't understand the devil. Didn't understand any of that. You can only push a child so far. You have laws; number one. And number two; I had been doing this so long, I could say now that I don't want to do something. But after a certain while, they knew when they had pushed their luck with me, and that it was time to, you know, maybe back off.

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.

I did a series for teenagers and kids called S-Club 7 in LA for Fox Family Channel. And I did it because the children, everybody's children, they don't know who I am. They know I'm the-lady-in-the-movie-they-can't-see. And I was actually offended by that because I think I've done a lot of wonderful work.
