Gromit: Wallace's dog companion 'nearly a cat', creator admits Plus, I had a packet of dog's noses from a craft shop, so Gromit became a dog. The cheese-mad inventor and his long-suffering pooch are to star at this year's BBC Proms, appearing with an orchestra at the Royal Albert Hall on a big screen.

Park added: "As they have only ever existed on film, this is a way of having a live experience with them." He also admitted that other than his own work, his three favourite animation films were "the first 10 minutes of Up," The Incredibles and Toy Story 3. The full interview with Nick Park is in this week's issue of the Radio Times.
