Chicago Reader review:
Samuel Fuller's directing debut (1949) is one of the most impressive on record, passionate and intense. Its protagonist is Robert Ford, the "dirty little coward / who shot Mr. Howard" in the back. Filmed almost entirely in close-up—the style that Jean-Luc Godard would later call "cine-fist"—this is agonizing, claustrophobic, and brilliant.
Here (and above) is an extract.
