I went back over the sketch books I'd filled at Sheffield for ideas and discovered Wallace and Gromit, except Gromit was a cat then. I made them into Plasticene shapes and started 'A Grand Day Out.' It took me longer than I expected.

As I get on and films take four years to complete, I tend to have a hankering for very short projects so you can move on to the next idea. It's the ideas I'm interested in. What comes out of your head.

My colleagues and I have to constantly remind each other that we must keep our own view on the world while making films. With 'Chicken Run,' we learned how easy it is to be influenced by outside forces, but you mustn't lose the heart and soul of what you are doing.

Many of Judy Blume's books - which I devoured when I was growing up and where I found characters that were believable because they were a lot like me - caused considerable consternation when they were first published, but now they're widely accepted as an essential part of the children's literary canon.

Though builders may build, in the main they follow the plans of architects. Teachers teach, but they must have a text. Politicians govern, but only upon the flow of commentary that raises them up or casts them down.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
