I saw this film in a Portuguese movie theater when I was visiting Lisbon years ago. I found it to be incredibly beautiful and mysterious. The French actor Claude Brasseur is really great in it and the whole feeling of the film reminds me of The Third Man. This director captured the city in an extraordinary way and plays with the camera to cross over the reality/imaginary line. Quite amazing. I returned to Lisbon years later and actually found the videotape for sale, so I bought it and have seen many times since. The music is by Zbigniew Preisner who wrote the music for Kieslowsky's The Double Life of Veronica.
