A real good WWII espionage film. With a host of actors and actress. Sophia Loren plays a very short part in this movie, about the shortest I've ever seen her play. The Germans are developing the V-1 Bomber and The V-2 Rocket Missile. The British must get within the German factories to provide bombing information or lost the war. Very interesting story line, with good actual footage now and then. The V-1 know as the flying Bomb a pilot less aircraft, The first V-1 was launched at London on 13 June 1944, one week after (and prompted by) the successful Allied landing in Europe. At its peak, over a hundred V-1s a day were fired at southeast England, 9,521 in total, decreasing in number as sites were overrun until October 1944, when the last V-1 site in range of Britain was overrun by Allied forces. This caused the remaining V-1s to be directed at the port of Antwerp and other targets in Belgium, with 2,448 V-1s being launched. The attacks stopped when the last site was overrun on 29 March 1945. In total, the V-1 attacks caused 22,892 casualties (almost entirely civilians). The V-2 Over 3,000 V-2s were launched as military rockets by the German Wehrmacht against Allied targets during the war, mostly London and later Antwerp. The attacks resulted in the death of an estimated 7,250 military personnel and civilians[, while 12,000 forced laborers were killed at the production of the weapons. This movie is outstanding and gets a 4 1/2 star rating.
