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

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.

When you're working with a script and you have three pages for that day, you have to shoot that. It can become sort of like a prison, because by the time you've shot what you need to shoot, you don't really have time to think or shoot anything else.

When people approach me about my films it is usually to tell me how much they hate them.

If you make a film set in London or in Pakistan or wherever, the thing that interests me is the relationships between individuals - individuals and society, individuals and their family, their girlfriend or boyfriend, it's all the same idea.

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.
