How did you interpret the ending? The way I see it, the entire film exists in the imagination of some guy contemplating a leap from a bridge. He has a fantastical daydream, creates in his head the consciousness of a perfect companion, and the repetition when they embrace at the finale is the moment of his leap in "reality". The final shot is therefore representative of him drowning (it's pretty obvious that the couple on the bridge are entirely different from the couple invented in this person's head. Not to mention, that several hours pass seem to pass in a split-second since it's suddenly morning). I think it's a brilliantly vague climax which allows for multiple interpretations of the film. May I ask, what was yours?
