Lust for Gold (1949) is a bookend narration-style lost goldmine murder greed and deception lousy husband historical western meets modern day media film noir of the western stamp, one of several noirs which combine past and present in a treasure huntin narrative.
All of which is made perfectly desperate by the acting of Ida Lupino, who does in the great noir tradition perform the most desperate of acting styles, making of everything a high stakes showdown, as is fitting of her role as the First Lady of Noir.
