Cloak and Dagger (1946): Fritz Lang’s WWII Thriller, Starring Gary Cooper and Lili Palmer (Strangers in Paradise)

In this Fritz Lang-directed thriller, Gary Cooper plays the mild-mannered Alvah Jesper, a physics professor at a leading university, who is drafted by the OSS (Office of Strategic Services) to enter Switzerland, and then Italy, just before the end of World War II.

Screenwriters Lardner Jr. and Maltz, who adapted (with others) Alaistar MacBain’s book, later became two of The Hollywood Ten, caught up in the power struggle between J. Edgar Hoover and the CIA. They were brought before HUAC, jailed, and blacklisted during the Red Scare

In the movie, Jesper’s mission is to locate Dr. Polda, an atomic scientist held captive by the Nazis.  While in Switzerland, he contacts Austrian scientist Katerin Lodor to get information on Polda’s whereabouts, but is spotted and followed by Ann Dawson, a Nazi spy.  Shortly thereafter, Katerin is brutally murdered.

Moving on to Italy, Jesper has a romance with an Italian partisan named Gina (Lili Palmer), who, along with Pinkie, has been assigned to aid him in locating Dr. Polda.  In disguise, Jesper visits the scientist who fears for his life.  Jesper is determined to remove Polda to the safety of the United States. Through a carefully worked out plan, the group smuggles Polda to a deserted farmhouse near a landing strip where a plane is to pick them up.

Although their escape is nearly averted by the enemy, Jesper and Polda board the plane, but not before Jesper promises Gina to return to her after the war.

Lang clashed with producer Milton Sperling over the ending and other issues. Sperling thought that Lang’s proposed conclusion about a discovery of atoic bomb was ridiculous, as the audience knew that the Germans had no nuclear capacity

Lang’s Preferred Ending

Jesper leads a group of American paratroopers into Germany to discover the remains of an underground factory, the bodies of concentration camp workers, and evidence the factory was working on nuclear weapons. Jesper remarks that the factory may have been relocated to Spain or Argentina, claiming: “This is the Year One of the Atomic Age and God help us if we think we can keep this secret from the World!”
