This is old-school filmmaking by a master of directing; Fritz Lang, creator of M and many other fine films. Cloak and Dagger was made shortly after WW2, so it has that real WW2 feeling that only films from the 40s have. The two major stars, Gary Cooper and Lili Palmer have a wonderful chemistry that works, as well as all of the supporting actors. The production values are first-rate; Lang would make sure of that. The storyline is interesting; spies for the A-Bomb during the war. Recommended for good WW2 atmosphere.
