There are two Americas - separate, unequal, and no longer even acknowledging each other except on the barest cultural terms. In the one nation, new millionaires are minted every day. In the other, human beings no longer necessary to our economy, to our society, are being devalued and destroyed.

Lawrence Gilliard Jr. is a fine actor and I've always felt some residual guilt that we killed him so early in The Wire. It was always planned that way; we didn't kill him because of anything he did, we don't kill off actors just to do it.

What appeals to me in The Deuce is some of the same things that made me interested in The Wire, which is there seems to be a theme here around markets and capitalism and labour. This is a moment, 1971, of something that was under the counter: then brown paper bags suddenly became legal, pornography. And it was really the birth of an industry which is now a multi-billion dollar American standard. And these people were the pioneers at a moment where there really were no rules, then suddenly there was a legal industry that was allowed to exist.

All stress is ultimately related to loss or the fear of loss.

Not only did this new pornography industry change the way men look at women and how we relate to sex, how we sell stuff, and not only did it change America's cultural landscape - it's also this incredible metaphor for a market-based economy. The great pyramid scheme that America has become. I felt like in were larger themes in terms of culture and economics that could be addressed.

What city has given the world more in terms of American culture than New Orleans? There is none. Not New York. Not L.A. Not Chicago. Not anywhere, in the sense that African American music has gone around the world twenty times over, and it's continuing to evolve. It is our greatest cultural export.

Our future can't be separated from the fact that we are all going to be increasingly compacted into urban areas, though we're different in race and culture and religion. And what we make of that will determine the American future.
