A good friend recommended this short piece to me (running time only around 60 minutes). For sure this was for its time (1955) a very experimental and daring piece with a fine tone of Film Noir, no dialogue at all but some good jazz tunes and some ghostly music. For our modern "eye" nothing that happens is that surprising or ueber-creative but if we take into consideration the time this movie was made, it must have been an astonishing piece to the audience. Dementia I would recommended to that kind of audience that is interested in the art and history of movie-making. Interesting.
