The Man Who Never Was/谍海浮尸

This movie is based on the Operation Mincemeat one of the most legendary actions in WWII, when UK sent a dead body with some fake letters to cheat German army to cover the attack to Sicily. The whole movie, though added with some extra but unnecessary plot, is very exciting and arresting.
