I've never done a film before where every single person in the audience knows the ending. I mean suspense, twists are almost impossible these days. People are blogging your endings from their cinema seats.

Film industry is a pretty brutal business. If you fall too far behind, all of the perfectionism in the world won't save you.

I love huge movies. Not sure I am the guy to make them, but you can rely on me being there watching them.

Your first film is always your best film, in a way. There's something about your first film that you never ever get back to, but you should always try. It's that slight sense of not knowing what you're doing, because the technical skills you learn - especially if you have a film that works, that has some kind of success - are beguiling. The temptation is to use them again, and they're not necessarily good storytelling techniques.

The most extraordinary thing, you'd be given permission for, and then the weirdest, simplest things, you just wouldn't be able to obtain permissions. And it would go on and on and on forever and ever, and there was no way to know. You have to kind of approach it with an open, quite optimistic mind, no matter what's thrown at you, because it will only ever result in damaging the film if you let any kind of despondency get to you.

Movies are about time. You can take that momentum and manipulate time as well, or you can deliberately slow it down, stop it, and start it again. There is no other art form that does that type of manipulation in that way.

It's interesting, the worse things get in cities, the tougher that cities get, the more brutal the humor is. The tougher things people face, the darker the sense of humor gets and I find that incredibly optimistic.
