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.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.

I think that there are cancers of the body, but I think they are what I would call cancer of the emotional system, too. These are the kind of diseases or illnesses or sicknesses of the emotional system that are as incurable as cancer.
