I don't know why people think child actresses in particular are screwed up. I see kids everywhere who are totally bored. I've never been bored a day in my life.
Well, I certainly was exposed to and learned to appreciate the work of great directors early on. As a kid, my mother used to take me to see really interesting arty films in Los Angeles.
Knowing what paint a painter uses or having an understanding of where he was in the history of where he came from doesn't hurt your appreciation of the painting.
It's an interesting combination: Having a great fear of being alone, and having a desperate need for solitude and the solitary experience. That's always been a tug of war for me.
