you have got to be totally honest and give advice and analysis that you’re asked to give that’s based on evidence. And if the analysis that you come to comes to a conclusion that a president might not like to hear that, you can’t be afraid of saying, “Mr. President, with all due respect, this is the way I think the situation is.”

We also believe in straight-talking, telling it as it is, using simple language that people understand, telling people about the downsides as well as the potential upsides, and even telling the bad news that no one wants to utter, like our lack of belief in the sustainability of the Icelandic financial sector that already we had months before the collapse hit us.

Well, that’s the optimistic reading of it, which you are never able to apply when it happens. You can read it this way when it’s over. Rationally speaking, it’s a period that’s needed, because the danger for every poet, I think, is to write too much. So these are the blessed moments of silence, protecting you from writing too many poems, diluting you and what you have to say in a stream of banal poems. It’s necessary, but still very painful, because I just don’t know what to do if I don’t write poems. I still survive, but it is painful.

I’ve had a long career as a writer, and a good one, in good company. Here at the end of it, I don’t want to watch American literature get sold down the river. We who live by writing and publishing want and should demand our fair share of the proceeds; but the name of our beautiful reward isn’t profit. Its name is freedom.

They’re very quiet coffee shops, and there are some positions in which it’s easier to write. Somewhere there’s an outlet, and you can keep your back to people. I’ll write for about two hours and then get up and walk with my iPad to the next coffee shop, about 10 minutes away. When you walk, you get a little fresh air, and I’ve heard moving around is good for you while writing. When you write in an office or at home, you end up sleeping. You can’t sleep at a cafe since you can’t lie down. I think that’s good, and it’s become a habit. I wrote Parasite half in Seoul and half in Vancouver.

I’m a rather slow writer and I have to go to a coffee shop. I turn my back to the crowd in the cafe, so that everyone’s chatting and the noise of the place rises behind me, and then I just keep my head down and churn out my screenplay. I can’t write at home, because I get too lazy. I’ll just want to watch TV or fall asleep. But I’m not allowed to lie down and fall asleep in the cafe, right? So it kind of forces me to work.

I wanted to create a very delicate and detailed film where you would feel like you could even smell every single character.
