Graffiti is one of the few tools you have if you have almost nothing. And even if you don't come up with a picture to cure world poverty you can make someone smile while they're having a piss.

Graffiti is only dangerous in the mind of three types of people; politicians, advertising executives and graffiti writers.

I think its pretty clear that film is the pre-eminent art form of our age. If Michaelangelo or Leonardo Da Vinci were alive today they’d be making Avatar, not painting a chapel. Film is incredibly democratic and accessible, it’s probably the best option if you actually want to change the world, not just re-decorate it.

The holy grail is to spend less time making the picture than it takes people to look at it.

Nothing is black and white, and there is no purity and there is no such thing has justice.

If at first you don't succeed, Call an airstrike.

We don’t need any more heroes; we just need someone to take out the recycling.
