35mm. A literally black film, carved by John Alton's cinematography, an unusual tale of secrecy, psychoanalysis, and mystical symbology, in the continuity of some Hitchcock's and Lang's and the mystery that invaded North-American 40's production. Is a perspicacious film, which director might be worth searching for - here rules an immensity of sculpted details, ambiences and points of view.
Quite simply, one of the most gorgeously photographed black and white films. The exquisite lighting is by the great John Alton. The acting is strictly "B" and the plot is convoluted but it does not matter. The look is everything.
