I'm always there at home thinking of Wallace and Gromit ideas.

After studying in Sheffield, I went down to London to do my post-graduate degree at the National Film and Television School, embarking on the movie that would eventually become 'A Grand Day Out.

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.

With some CGI, I think the brain slightly perceives that things aren't real. There's no gravity, the light's not quite real, the shadows aren't quite real.

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

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.

Gromit was the name of a cat. When I started modeling the cat I just didn't feel it was quite right, so I made it into a dog because he could have a bigger nose and bigger, longer legs.
