"I don't sign that one. It feels very uncomfortable. Why would you do that? ... People ask me to sign that one a lot, and actually there's a photo of it as well that someone's lifted from a still of the film. That photo gets passed around. It's like, 'No, I didn't mean for it to be a photograph that I would end up seeing 16, 17 years later.' It's still haunting me. It's quite funny really."
