"Every time I show this, it plays differently. Some people think it's about animals. Some people think it's about life and death. I've shown it to a group of bankers, who believe it raises all kinds of questions about success, about starting a small business. People think it's funny or sad or deadpan or satirical. They think that Errol Morris loved the people in the film, or that he was being very cruel to them. I've never yet had a person tell me that it's a bad film or a film that doesn't interest them.""
