The Big Blockade on AllMovie

Having underestimated Hitler in the 1930s, British propaganda specialists spent the early war years insisting they were prepared for any international contingency. Big Blockade was a morale-boosting film produced in cooperation with the Ministry of Economic Welfare. In documentary fashion, the film underlines the importance of the economic blockade which Britain directed against Germany. An all-star cast (Michael Redgrave, Leslie Banks, John Mills, Robert Morley etc.) appears in brief sketches dramatizing the effect of the blockade and the reactions of the British public. While it received good reviews at the time, The Big Blockade quickly fell out of favor once it served its wartime purpose.
