A lot of the aspects of the world of the film are amalgams of things that already exist.

I don't particularly like the idea that there's an arc to the story and that therefore in this scene you have to convey this bit of information or emotion. I like more the feeling that, of course, there is a shape to the story, but that each scene should feel right, should be true at that moment, and that gradually you accumulate these moments of truth until you get enough of them together that it becomes a story that's interesting.

We always had the idea that there might be two slightly different versions of the same thing.

I prefer to take actors and put them in real settings and real locations and real situations rather than create artificial locations that serve the characters. It's just much easier when you are walking down the street with your actors to do that in a real street that's still open with people on it, rather than to close it off and bring in extras.

There's still a 1950s view of cinema, that there's one audience and they all want to see the same thing.

There's a lot of ridiculous hypocrisy about sex in films today. And that's one of the reasons why I made 9 Songs, to say, "Why can't you put sex in a film?"

From my experience working with comedians, there is that competitive aspect. With actors, for instance, they don't want to look competitive even if they are, whereas comedians, I think, are openly happy to play on the idea that they all compete with each other to get the laughs. There's something about comedy, I think, that encourages that. There's this kind of schoolboy sense of wanting to top the other person that we play off of to show them competing for who's smarter or cleverer.
