In big battle scenes, like 'King Arthur', you see the knights in all their fine armour, but they're not in the thick of it: follow the perspective, and you'll find some poor little sod, who didn't want to be there, anyway, with his head split.

I have been lucky with writers. None have been real trouble. Some I never met. Some I meet only after the book is finished, and some, the easiest to get along with, are the dead ones. Most become friends.

The seed of an idea laying dormant in an old sketchbook is fed the missing ingredient from a new experience. Trying to share some of these experiences, some of the wonders, is one of the reasons why I do books.

Drawing was the only thing I was any good at in school, but I never dreamt I would, or even could, spend my life doing it.

I write a lot about other people, like family and friends. I look at their lives and relationships and think, 'Well, if I was in your position, this is how I would see it.'

These people living on the streets could have been friends you once knew. They are people who have somehow fallen through the gaps and found themselves, often through unimaginable circumstances, on the cusp of existence. In another reality, this could easily be me or you.

I've always had an uneasy relationship with technology and how it insinuates itself into our lives: for example. I always prefer talking face-to-face with friends than texting or calling, and if I want to get updates on their lives, I don't go to Facebook but meet them in person.

It's so great to be able to express the friendship between men.
