All romances end in tragedy. One of the key people in a romance becomes a monster sooner or later.

For me, it's just a normal artistic endeavour to explore the dark side. Certainly, I'm not alone in it. Artists generally don't like to accept the version of reality that society and culture hand them. They want to know what's really going on. So you're always looking in the ceilings, under the floorboards and behind the walls, trying to find the mechanisms, the structures, and the truth. I find that often leads you into some dark places.

I can't imagine a life without humor. Especially if you have an existential understanding of life, you must acknowledge the absurdity of it all.

I work with my dreams or nightmares.

We are at a major epoch in human history, which is that we don't need sex to recreate the race. You can have babies without sex. This is the first time in human history that has been true, and it means, for example, we could do some extraordinary things.

Let's put it this way, when I was casting, I cast Viggo first and then found someone who could play his wife, rather than the other way around. So for me he's still the lead character.

But when you're writing a script - for me anyway - you have to sort of create an enforced innocence. You have to divest yourself of worrying about a lot of stuff like what movies are hot, what movies are not hot, what the budget of this movie might be.
