Freaky look at post-WWII Nazis living in hiding, plus one concentration camp survivor (Charlotte Rampling) reliving the horrors of the past. When she and her tormentor (Dirk Bogarde) -- now the night porter at a Vienna hotel -- re-encounter one another, they relaunch their sado-masochistic freakshow of a relationship. Of course, Bogarde's pals want 'the witness' gotten rid of. More disquieting than gruesome, The Night Porter launched a series of similar films that got progressively more and more explicit. Still, there are a few to many soliloquies and odd non-sequiturs (solo male ballet, anyone?) here, serving to pad the film. Still, groundbreaking might not be the right word, but it's certainly the right sentiment.
Aka Il Portiere di notte.
