An awesome, dark & atmospheric film. Gish is superb as the fragile Letty driven to the brink of madness by the incessant wind whipping up the sand. Her portrayal, with her wide staring eyes & tensing hands as the madness threatens to overwhelm her is stunning. The film takes its time to establish its characters, with a constant backdrop of the menace of the environment & also the danger of violence & the descent into madness, building to a thundering & almost unbearably tense experience with the actual sand storm itself. A true classic of the silent era capturing a performer at the peak of her powers-the image of Letty staring wide eyed through the window as the sand uncovers the body will stay with you.
