Screen siren Hedy Lamarr was more than just a pretty face. She also co-invented a secret communication method, based on spread spectrum technology, which is used to guide torpedoes.
A new stage play, Frequency Hopping, looks at Lamarr's unusual life. Playwright and director Elyse Singer talks about her dark comedy based on the collaboration between Hollywood's glamour girl and "bad boy" composer George Antheil.
