My father, an architectural photographer, was an incurable tinkerer, maker and mender.

We can do things that we never could before. Stop-motion lets you build tiny little worlds, and computers make that world even more believable.

When I was a teenager, my dad watched my films and told me I could go to art college and study animation. He made me see that I could do this for a living.

I have to admit to not being the greatest technician, but stop motion animation gives me licence to create machines that wouldn't otherwise be possible - inventions that seem real and actually work.

But I think people see 'Wallace and Gromit' as something akin to an elderly couple. These two know each other so well. Nothing can split them apart.

If you respect the audience enough, they can take onboard many things.

I think we all have a Wallace and Gromit inside us. Wallace is the part that has wild plans. Gromit is the sensible side, reining you in.
