Lady Eve (1941)

This is another Preston Sturgiss film, starring Barbara Stanwyck as an adventuress who has lured a rich but unworldly young bachelor, Henry Fonda,  to her cabin on an ocean liner, and is skillfully tantalizing him.  Stanwyck plays Jean Harrington, a con woman who travels first class with her father and their valet, fleecing rich travelers in card games and whatever else comes along. She sets her sights on Charles Pike (Fonda), heir to a brewery fortune, as he comes aboard after a snake-hunting expedition in South America.
What is both skillful and irritating about Stanwyck's performance is how she has it both ways. She is a crook, and yet can be trusted. A seductress, and yet a pushover for romance. A gold digger, and yet she wants nothing from him. And he is a naive innocent. She falls for him so quickly and so thoroughly that she's even frank about her methods; just before he kisses her in the moonlight in the ship's bow, she tells him, "They say a moonlit deck's a woman's business office.”
The thing is that we are watching this movie against the background of #MeToo, the stripping of women of autonomy by the current administration and the incredible entitlement of the upper class demonstrated by Brett Kavanaugh.  So it fell a little flat.
