This is something of a Dual Film Fatale entry, given that it's a documentary about Hedy Lamarr directed by a woman.
I was looking forward to a film showing how Lamarr's work as in inventor was buried underneath her image as a great screen beauty. And that topic is always in the background. But much more of the film than I expected is devoted to Lamarr's career as an actress. And that career is not the most interesting thing about Lamarr. I wanted a movie about an inventor who was also an actress, but what I got was a movie about an actress who was also an inventor.
Obviously, the two go hand in hand. And the time spent on her acting career does establish a setting whereby Lamarr's intelligence might be ignored. Dean is kind enough to avoid much analysis of Lamarr's acting ... her fame came from her beauty, not because she was a great thespian.
I'm wondering if they spend relatively little time on her inventions because they weren't as engrossing for the audience than just showing pictures and clips of her in her prime. I don't want to press this point too much ... Dean does not ignore the inventor in favor of the beauty ... but it's the inventions that make this story more than just another tale of a Hollywood goddess.
Nonetheless, Lamarr's life story is a fascinating one, and a documentary is the way to go. The information is here. Lamarr was as smart as she was beautiful.
