There are various kinds of savagery: emotional, spiritual, economic, and cultural savagery.

What happened with the opioid epidemic is the Mexican cartels made a very deliberate, corporate decision to undercut the price of opioids. What they discovered was they could increase production, increase potency and decrease the price, and sell it for a third of what the Big Pharma could, or street dealers could, for Big Pharma pills. North America, and to a slightly lesser extent Europe, is being flooded with this Mexican heroin as a direct result of the attempt to undercut American pharmaceutical companies.

That sounds like Anthony Soprano. He has a point. I've said it before: if you're black and you sell dope, you end up in the big house; if you're white and you sell a large amount of dope, you end up visiting the White House. So it's a matter of race and it's a matter of scale, frankly.

Shane Salerno and I adapted my book Savages together, and I learned a lot about adaptation. I think it's an extremely difficult thing to do; adaptation might even be more difficult than writing an original screenplay. It's so much a matter of choices, making choices of what to leave in. It was an education.

I'm a jazz guy and a Bruce Springsteen guy. So I wanted something more current, and edgier, and angrier. So I asked my kid to educate me about hip hop; he has an encyclopedic knowledge of it. And he did so. I found it to be much richer than I would've thought. I think some of the poetry in it is really spectacular. I threw rap into the book. I think I mentioned Kendrick Lamar. I'm really into Tupac these days. I love Nas, N.W.A.

I think one of the problems with being a fiction writer these days is that you can't keep up with the headlines. Things that people would say are absurd occur the next day or they come out of somebody's mouth. There are days I just wanna give up.

We need to do something about gun violence in America. But every time one of these things happen, we say the same thing, and then we don't seem to be able to do anything. And that needs to change.
