I don't think anyone really understands why a show works or why it doesn't.

Each week the machine is spitting out a number for a new person or a new world within New York that you get to know. And the idea from the beginning was that some of the characters would stick around and become part of the lives of the show, and the world of the show itself will continue to grow.

I've always been interested in themes of memory, paranoia, and revenge.

For me, the attraction of TV is that you continue to get to tell those stories and refine those characters. The other thing is that TV, in the last years, got really, really, really good.

Typically with HBO shows, the ninth episode often winds up being a big one and when lots of exciting stuff happens. And then the tenth one is the more placid, character-based one.

I'm a big believer in practical and location photography.

I've worked in the movie business for many, many years, where you have lots of days and lots of money. It's really mainly about time. We always try to conceive all of our action from a place of, "What can we shoot that looks fantastic?," rather than trying to do the kinds of thing that you would be able to accomplish in a movie.
