Vivid World War II documentary. It gives a detailed account of the Nazi blitz on Britain, which opened on May 10, 1940, and ended a year later with England bloody but unbowed and all Nazi hopes of invading the island rudely dashed. The material, culled from British and German archives, has been shrewdly edited and, for the first time, the Battle of Britain is seen from the Luftwaffe's viewpoint as our own. Alistair Cooke's commentary securely welding the whole, is first-class, and the quality of the photography amazingly consistent. The picture, brilliantly edited by Harry Booth, turns back the calendar 20 years and shows the strafing Britain's civilian population endured during the Battle of Britain, finally won by the RAF. Its salient scenes, which include the recruiting of women for the services and industry, children being evacuated and Dunkirk's abandonment, and appropriate extracts from Winston Churchill's famous speeches, strangely enough, give a nostalgic touch to the grim and glorious backward glance.
