I mean I think one of the larger problems going on right now is, debate has replaced discussion. As I say you can't lump Wall Street into one category. That doesn't mean anything. Every firm has a different attitude and does different things and puts their cherries in certain places and their money in others. Some are vicious, nasty, I will cut you down at all costs to make a buck, some have a much higher moral standard.

I remember talking to my dad about legalization in a book we did together called "The Big Empty." He was saying like, "Oh, no, no, as soon as it's legalized it will be ruined." "The corporations will get their hands on it. You'll have, you know, pot with vitamin C and, you know, 'Viagratized High Toke.'" You know different things like that. That it won't be, you know, they'll put chemicals into it. It won't be that pure plant that it is now. He may have a good point there.

It seems to be the sense that once you throw guys in prison they're not going to come out. No, they're going to come out and, you know, what kind of beast have you created from that process?

One of the things that sets Oliver Stone apart though is he is commercial. He is mainstream. He makes big movies and he is one of the last guys that can make big movies that actually have something to say, that you know challenge the audience in a way while entertaining them.

My father, Norman Mailer, expected a lot from us and he really pushed us and you know one of his favorite lines was, "If you think I'm being hard on you, wait until life hits you because life is a hell of a lot tougher than I am." And I took everything he said to heart. He taught me how to write, which was scary and intimidating and hard, but ultimately one of the biggest gifts I could have ever asked for.

I was about 20 when my mom got sick with cancer and it was bad. It was very scary and at the time I was doing my first screenplay and I was on deadline and was alone with my father in Massachusetts. I said, "Pop, you know, I don't how I'm going to work. I don't know how I can get this done. You know, I got to hand this script in and I can't think about anything but Mom." He said, "Well, you know, now is the time when you're going to learn what it means to compartmentalize." And those words really had an impact on me.

There's also just socially, personally. There is something naughty about pot. There is something that is rebellious and outlawish and a kind of, you know, a finger in the eye of the government saying, hey, you can't tell me what to do. That would be gone if legalize it.
