Hedy Lamarr was called the most beautiful woman in the world during her days in Hollywood and you can see why in some of the pictures they show but the thrust of this story is her great work during WWII on frequency hoping which technology has led to WIFI, GPS, Bluetooth, etc. No one wanted to believe this beautiful woman was capable of accomplishing this work but this documentary goes step by step in showing it is in fact true. Hedy was one unique human being and possibly the most interesting movie star of all time.
