David Lynch is not like other directors. Critics say his films make no sense and even he admits they are difficult. But he also adds to his air of mystery by doing things like taking a cow for a walk on a busy Los Angeles intersection or deciding to become a coffee merchant so moviegoers can drink his coffee while watching his films. Lynch says he walked the cow on a leash because everyone likes a cow. When a young woman the other day asked the cow’s handler if she could pet it, he said, “No, the cow’s working.” Arthur Spiegelman reports.
