This film about surface and inner passion (derangement, fear, etc...obviously symbolized by the pool) is a pleasure, mostly through the performances of Alain Delon and Romy Schneider. Most of the plot lies under the surface and there are many scenes where one must read between the lines to understand where everything will lead to. Okay, the film could have been a bit shorter, but the actors in my opinion really make up for it. We've seen everything now in the movies - but still, the opening sequence is one of the hottest scenes ever filmed. I cannot explain, see it yourself.
