In 'Bombshell,' The Double Identity Of Hollywood Star Hedy Lamarr

In Alexandra Dean's new documentary, the stunning silver-screen beauty of the 1930s and '40s is also the inventor of a technology that makes today's wireless encryption possible.
Film actress Hedy Lamarr, pictured here around 1955, was both a major star on screen and an inventor by night.

If you're reading this through some kind of Bluetooth or Wi-Fi gadget, here's an interesting fact: Some ideas behind that technology can be traced back to a famous actress from the 1930s. Her name was Hedy Lamarr.

The story of this stunning beauty of the silver screen is told in the new documentary Bombshell. From a scandalous debut in the pre-war European film Ecstasy to Hollywood films including Algiers and Samson And, the documentary tells little-known details of how she was worked grueling days by Hollywood producers and spent her nights in her own laboratory where she loved to invent.
