The Strange Woman (1946)

Hedy Lamarr is a beautiful but manipulative young woman who finagles a marriage to the richest man Gene Lockhart in town but then coerces his son Louis Hayward to arrange for the death of his father. She later sets her sights on her best friend’s fiancé George Sanders. It’s not often such a cruel, devious woman gets to lead a film and Lamarr uses her beauty to great effect. The ending is a bit of a let down in its contrived reversal, but it’s a intriguing ride getting there.
