A really terrific French movie from the 1950's is on blu-ray today. One of the greatest heist movies of all time from director Jules Dassin, it's about a gang of criminals who commit the almost impossible task of robbing one of the most secure jewelry stores in Paris. The look and feel of this movie is perfect, it's all smoky atmosphere and 50's jazz cafes in Paris- and the actual heist sequence is one of the most famous of all time. Definitely look for this, it's suspenseful, exciting, dark and completely modern in tone.
