Mr Bunting was the most challenging character for us to design. Visually, there may be a link between the book and the film, but it’s not really clear within the book about why he’s feeding on the imaginations of others. I needed to think long and hard about the reasons why and then I came to my conclusion: it’s about reality. It’s something that you can’t ever escape. It’s always there. The reason I thought about that is because A.F. Harrold is a poet himself so there must be metaphor behind it, and it must be the metaphor of reality. It’s how Bunting behaves that creates the scariness. It’s not that obvious whether he’s a scary character or not from the beginning just by looking at him. And I wanted to really make that ambiguity. There’s a strong link between the visuals of the book and what ended up in the film.
