Any discussion concerning the greatest foreign films of all time must include (but often does not) Krzysztof Kieslowski.  'Double Life of Veronique' and his 'Three Colours Trilogy' are perhaps the most thoughtful interpretations of modern society.  Double Life is hypnotic and moves into the realm of surrealism.  The imagery is meticiously crafted and the soundtrack is creepy as hell.  The film will have you talking long after the credits have ended.  The 3 colours trilogy is a masterwork and should be watched in the order they were filmed; Blue, White and finally Red.  Each deals with the respective colors' meaning according to the French flag (Freedom, Equality, and Fraternity).  Kieslowski was an artist with a very acute sense for detail, every sound, every movement of the camera, every nuance seems to have been thought out to fit the films theme.  His death a few years back has left a giant hole in cinema's heart.  He was the greatest living filmmaker of his time and it is unfortunate for us that there are so few of his treasures which actually came to be.  What we do have are a few masterpieces, dropped off by a genius on his way to other worlds.
