Hollywood star Hedy Lamarr (Ziegfeld Girl, Samson and Delilah) was known as the world's most beautiful woman—Snow White and Cat Woman were both based on her iconic look. However, her incredible beauty stood in the way of her being given the credit she deserved as an ingenious inventor whose pioneering work eventually helped revolutionize modern communication. Mislabeled as “just another pretty face,” Hedy’s true legacy is that of a brilliant technological trailblazer. An Austrian Jewish émigré, she wanted to help defeat the Nazis. She invented a covert “frequency hopping” communications system to make Allied torpedoes unstoppable, and then patriotically gave her 1942 patent to the Navy, who ignored it and told her to sell kisses for war bonds instead. Throughout her life few knew of Hedy’s secret history, but in 2016 director Alexandra Dean and producer Adam Haggiag unearthed four never-before-heard audio tapes of Hedy speaking about her incredible life. Combining this newly discovered interview with intimate reflections from her children, closest friends, family and admirers, including Mel Brooks and Robert Osborne, Bombshell finally sets the record straight, giving Hedy Lamarr the chance to tell her own amazing story.
