I want it to be able to hold up in 30 years' time. So, I'm really thinking about everything.

'Eraserhead' is a weird, horrible nightmare, and it doesn't narratively make sense. Stuff's happening, but you honestly feel like you're in a nightmare, and it has such disturbing imagery that it stays with you forever once you've seen it.

All the copycat movies were always PG-13 and people said: "Nobody wants violence."

You can pretend everything's fine, but if there's an unhappiness or you're not having sex or you're not communicating or you're made to feel third best in the house and you don't address it and you just try to put on a nice face and a smile, that kind of aggression and anger is going to come out in some sinister way.

I think in life we get very caught up in the minutia and, unfortunately, it generally takes some sort of tragedy in your life to put things in perspective.

I think characters are most terrifying when they're relatable. It's best when your most horrible characters make sense, and are believable. That's when a movie is most terrifying.
