I have a theory that if The Marquis de Sade wrote a screenplay adaptation of an Agatha Christie novel and David Lynch directed circa Eraserhead then the resulting film would not be unlike Singapore Sling. I mean that neither as recommendation or repudiation, but certainly as admiration.
Which leads me to a couple of questions. Not that it matters, but wouldn't a bold imagination such as Sade find the streamlined and generic sex games and accompanying uniforms used in his name to be banal? And why do we hear so little of Leopold von Sacher-Masoch, aside from the odd Venus in Furs reference?
