Seamlessly interweaving archival war footage and a fictional narrative, Stuart Cooper’s immersive account of one 20-year-old’s journey from basic training to the battle front lines at D-day brings all the terrors and isolation of war to its viewers with jolting authenticity. Overlord, impressionistically shot by Stanley Kubrick’s longtime cinematographer John Alcott, is both a document of WWII and a dreamlike meditation on man’s smallness in a large, incomprehensible machine.
