She co-starred with Clark Gable and James Stewart and was Delilah to Victor Mature’s Samson in the blockbuster biblical epic.
However, Bombshell: The Hedy Lamarr Story proves that she was so much more than a pretty face.
Lamarr had the most brilliant mind.
During the Second World War she devised and patented a system of frequency hopping that stands as a significant building block on the way to the wifi and Bluetooth that we take for granted today.
But the recognition she deserved never came.
Patronising men told her she could better serve her adopted country entertaining troops rather than worrying her little head with inventions.
Alexandra Dean’s fascinating, poignant documentary is based around a lengthy audio interview with the late Lamarr (right) which allows the film to unfold in her own words.
She lived an amazing life, tasting all the rewards and pitfalls of fame. But this is a woman who never had the chance to show her full potential.
