When I started my goal was to make a successful underground movie. I started making movies in the mid-60s. Underground cinema then only lasted about two or three years.

I think it's important to visit people in prison. And if you know anyone in prison, I would encourage you very much to visit them. They're a good audience! I always get good letters from prisoners. I don't usually answer them because I have a lot going on in my life, but I get some really good ones, I get some really good letters from prison.

I used to joke that I was trying to sell out, and nobody would buy me.

It took me a while to figure it out, but to have a real hit on Broadway, you have to get the respected Broadway people to like it. But then the production also has to appeal to the most middle-class people who know nothing about Broadway and who come to see it later.

Get on the fashion nerves of your peers, not your parents - that is the key to fashion leadership.

I'm always amazed at friends who say they try to read at night in bed but always end up falling asleep. I have the opposite problem. If a book is good I can't go to sleep, and stay up way past my bedtime, hooked on the writing. Is anything better than waking up after a late-night read and diving right back into the plot before you even get out of bed to brush your teeth?

There are little things that get on my nerves, like people who have reading material in their powder room. When you go in someone’s house, and next to the toilet they have a huge basket of magazines, I find that repellent. I recommend against straining while reading.
