Of course subjects are changing, and since I started so early in filmmaking, I did my first film at age 19, of course you grow up with your films and you are not trotting the same path all the time.

Of course I do things in my voice in my commentary, which I wrote.

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.

It's curiosity, and always a sense of poetry. You see it in particular in the chapter "Iceland" where I'm reciting ancient Icelandic poetry. It has this very beautiful gravitas in conjunction with the volcanoes.
