With Joan Crawford and an incredible four husbands in one movie, there are questions galore in the damned darkness of The Damned Don't Cry (1950).
Joan Crawford's character starts with a husband that she does not rate, even though it is Richard Egan. But he's too controlling and penny-pinching for her, and she is a film noir hero for whom enough is not enough.
Rephrasing that, this is a common enough film noir lesson: you are not satisfied with your mediocre and quotidian suburban working life, or as in this case, a rather blue collar existence on an oilfield.
