In one of the scenes the American Flag has fifty stars, as it does now, but that flag was not adopted until Monday, July 4, 1960. The flag that should have been shown, which the Americans during World War Two served under, was the forty eight-star Stars and Stripes, which was valid from Thursday July 4, 1912 to Friday July 3, 1959, and is even seen hanging high in Grand Central Station in Hitchcock's North by Northwest.
