Chicago Reader review:
John Huston's bleak, semidocumentary account of a jewel heist and its moral consequences. One of the first big caper films, this 1950 feature contributed much to the essence of the genre in its meticulous observation of planning and execution. But Huston's interest remains with his characters, who dissolve as tragically as the prospectors of The Treasure of the Sierra Madre and the adventurers of The Man Who Would Be King. The film has been remade at least three times, as The Badlanders, Cairo, and Cool Breeze.
Here (and above) is the trailer.
