Juan Pujol garcia, s Spaniard, aka Garbo, was a double agent, feeding information to Nazi handlers, who thought he was their agent based in England. He gave the Nazis, who thought he was their spy, information the British gave him to relay and thus was instrumental in misleading the Nazis so they thought the D-Day invasion was to take place in Pas de Calais rather than on the Normandy coast. The true story was interesting, told through interviews, snippets of movies and what appeared to be newsreel footage but the film jumped all over the place, back-and-forth in time and place, and too-loud music drowned out some parts. Fortunately subtitles were available and readable
