Perseverance has kept me going over the years. Things rarely happen overnight. Filmmakers should be prepared for many years of hard work. The sheer toil can be healthy and exhilarating.

When the camera is looking back at our planet Earth, it's the tiniest of specks somewhere out there in the universe. So we do have a new sense of proportion. Of course the volcanoes and the magma under us just remind us of that.

There are deeper strata of truth in cinema, and there is such a thing as poetic, ecstatic truth. It is mysterious and elusive, and can be reached only through fabrication and imagination and stylization.

Facts sometimes have a strange and bizarre power that makes their inherent truth seem unbelievable.

Of course there's a value in a storyboard if you do a big - let's say an action movie and actors have to move and act in front of a green screen because entire backgrounds exploding and cars flying through there have to be created separately, and in this case you better make sure the actors are precisely placed and the background action is moving in a certain moment, for this type of film you would need a storyboard.

We live in a society that has no adequate images anymore, and if we do not find adequate images and an adequate language for our civilization with which to express them, we will die out like the dinosaurs.

You should bear in mind that almost all my documentaries are feature films in disguise.
