An Outsider's Perspective on Horror

This is an attempt to look at horror from a different angle. This is a list of horror films directed by people who only ever took one stab at the genre. The guidelines are simple: their contribution can’t have been their first film and they can’t have tried it more than once. I hope to examine the line where art and horror meet and see what our most respected auteurs get up to when given license to draw blood. TV and/or short films do not count.
