There's digital fatigue. When you can do everything, you can actually do nothing.

We consider the Holocaust as being a sort of strange event taking place on another planet; we never understood in a visceral way that this is something that took place in the heart of man. That's something that you can feel, the genocidal tendency is within human nature. It seems that if we forget about this, our future is also compromised.

There are genocidal tendencies that are at the heart of the human potential, and I think if we don't talk about it, we're not preparing ourselves for a better future.

Sometimes all we need is only listening to an inner voice and remaining human in a very personal way. But even if it is a personal way, it's still a very valid way - maybe the most valid way. It doesn't have to be a collective experience or someone telling you what to do. The most sacred human experience can be a very personal one.

When I began research, I read the writings of the Sonderkommandos. They are not well known, but these prisoners wrote from the middle of hell from Auschwitz, to let the world know what happened. The texts were buried beneath the ground and found after the liberation of the concentration camps.

We have progressed in a technological sense, but I'm not so sure whether we have progressed in a civilizational matter - the quality of the civilization has not improved. It's a civilization that's in love with technology but forgetting about the human side of it and the destructive tendency in human civilization has not been faced.

I really wanted to take the viewer to the 'here and now' regarding the exterminations, and communicate directly in a visceral way. The art of cinema can communicate that way, and that's why I wanted to do it that way.
