- John Lasseter: Gromit is one of my favourite characters ever created in animation. And he never speaks. Yet there's so much expression in him.
- Merlin Crossingham: It's all about body language and the way his face presents itself to the camera. And making your audience understand what he's thinking without saying a word - it's so difficult.
- Martin Freeman: I've seen less capable comedic human actors than Gromit. What he can do with a look is sort of Stan Laurel-esque. It's approaching genius, if not actual genius.
- [talking about Nick Park's choice of her to play Wendolene in 'A Matter of Loaf and Death']
- Anne Reid: I said to Nick "Why did you choose me?" And he said "Well we saw you on television and we thought your voice sounded as if it came out of a puppet." I said "Oh really? I'd never thought of that!"
