You use words like 'introvert' and 'extrovert,' various traits of a personality. A lot of that stuff, we used in drama school, and that was kind of interesting, to realize my teachers sort of ripped off a lot of Jung. And how much of it is part of our society now, these phrases, introvert and extrovert, where it actually came from.

There's so much going on in the world. There's so much information being thrown at us - so many things are being sold to us, and we're being told how we should appear and how to be more successful, blah, blah, blah. How does that manifest itself? In the pressures, the stress, this need to escape.

Once I could drive, I spent all my time in the city going to metal shows. I missed the first couple of Metallica shows because I was lame. By the time I got into them, they were playing places like the Kabuki.

I spent lunchtime in a grave during the filming of 'Bloody Mama.' When you're younger, you feel that's what you need to do to help you stay in character. When you get older, you become more confident and less intense about it - and you can achieve the same effect.
