While you are walking you would learn much more about filmmaking than if you were in a classroom. During your voyage you will learn more about what your future holds than in five years at film school. Your experiences would be the very opposite of academic knowledge, for academia is the death of cinema. It is the very opposite of passion.

I was able to persuade them to let me shoot in areas that were beyond the volcano itself. Beyond the joint scientific program between Cambridge University and North Korean scientists. I was able to film in a kindergarten, subway, other things you would not normally be allowed to do.

North Korea is not an exception. Even there, where you think it would be completely sober, they have the myth of their revolution being connected to the volcano.

Centuries from now our great-great-great-grandchildren will look back at us with amazement at how we could allow such a precious achievement of human culture as the telling of a story to be shattered into smithereens by commercials, the same amazement we feel today when we look at our ancestors for whom slavery, capital punishment, burning of witches, and the inquisition were acceptable everyday events.

May I propose a Herzog dictum? Those who read own the world, and those who watch television lose it.

I know whenever it comes to be really dysfunctional and vile and base and hostile on screen, I'm good at that.

Otherwise you have to repeat a lot when you're filming. And I've seen the film and it's in a border town in Mexico close to the border with the United States, so of course you have a lot of traffic and noise and dogs barking right nearby, and for that you have to repeat a lot and Robert Rodriguez didn't do that. Smart, smart, smart, you better have smarts also.
