Cool movie from the director Roman Polanski. Unreal atmosphere, among dream and reality. But the unforgettable scene was without any doubts the dance between Harrison Ford and Emanuelle Seigner. I call it the snake dance! A must to see but a must to listen: Grace Jones with Libertango. Actually I can't remember a dancing sequence like this....I just make exemption for the tango scene in True Lies :)
