I like and I love everything that has to do with cinema, writing, directing, editing, creating music, and even acting.

Ten years ago in Antarctica shooting "Encounters at the End of the World," I met a very fine volcanologist from Cambridge University [Clive Oppenheimer] and we kept talking about doing a film and all of a sudden it became serious when he hinted at the possibility to film in North Korea.

I always felt completely confident - it's like in a feature film, knowing your principle character is extremely well-cast. I had that same confidence in Clive [Oppenheimer].

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.

If I had to climb into hell and wrestle the devil himself for one of my films, I would do it.

In Germany, you would be hanged if you cracked a joke about Hitler and you would be killed by the state if you were insane in a project of euthanasia.

I think a state should not be in the capacity of killing anyone with the exception of warfare.
