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.

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

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.

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.

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.
