Bombshell: The Hedy Lamar Story [Blu-ray]

This profile of 1940s movie star Hedy Lamarr sheds light on a mostly forgotten aspect of her life: her work as a trailblazing inventor. Lamarr developed an advanced communication system for the U.S. Navy in order to help defeat the Nazis; decades later, her innovations are still being used in Bluetooth and Wi-Fi. Directed by Alexandra Dean.
