Hollywood star Hedy Lamarr was considered one of the world’s most beautiful women. Born in Austria, and invited to Los Angeles after her notorious nude scenes in the 1933 film Ecstasy, she would soon play opposite the biggest stars of the day. However, her looks and glamour stood in the way of being recognized as an ingenious inventor who helped revolutionize modern communications. During World War II, she and composer George Antheil developed a system that is now used as the basis for secure WiFi, GPS and Bluetooth. But nobody knew this at the time. Combining newly discovered interviews with reflections from family, friends and fans (including Robert Osborne and Mel Brooks), this documentary brings her accomplishments to light. Writer/Director: Alexandra Dean. (US 2017) 89 min.
