Very, very often in movie sex you see this fiction about unity. A union. That somehow these two thinking beings become one, and there's one action and they're sort of perfectly in sync, and the lighting's perfect, and they've got their eyes closed, and they're gone, you know? And then you cut to someone having a cigarette. And it's all so much Novocain. Meanwhile, those of us us watching it are going "I'm never going to tell anybody, but I never have sex like that".

Daily absorption in the physical actualities of nature is life as I need it to be: it means I am connected to such large things - sky, sea, hill, the vagaries of weather, the undeniable needs of animals - that I can disappear as a subject of interest, I can exist without self-consciousness. The city is a challenge for me, however thrilling a few days prove, for its insatiable overstimulation and the rarity of quiet. The city makes people bigger than they need to be.

When I say that it's taken us [with Luca Guadagnino ] 11 years to make this film, what I mean is that it was 11 years ago that we started to talk about a kind of cinema that we wanted to make together.

It's exotic for me to be given a script that's already written, and be given a pay cheque, and asked to dress up and play, and that's all.

I would say, and this sounds like a rather immodest thing to say, but the truth is it's probably the most amazing thing of all, it's pretty much exactly what I thought we were going to make, what I hoped we'd make.
