Secret Agent (1936)

Secret Agent (1936) is a wacky and serious by turns British historical continental espionage thriller by Alfred Hitchcock, and one able to pull a rather outré punch with its oddity, hilarity, dark subject matter and casual approach to high European super spy-work.

Either way the debonair humour and sophisticated violence and random fantasy involved in this type of fancy spy work is going at some point in the future, and maybe after being re-emphasised by Hitchcock in his masterpiece North By Northwest (1959) be reminiscent of the British Bond, and indeed if you were to ever ask who might have been the first British actor to play such a thing, the answer may well be that it is John Gielgud.

That is correct. Gielgud as Bond. He even does the Mrs Female Spy only one bed for Mr and Mrs Bond in a hotel room routine, so why not.

Cloak and Dagger (1946)

Cloak and Dagger (1946) is a Nazi nuclear secrets behind enemy lines espionage thriller made partially in the film noir style by Fritz Lang, starring Gary Cooper and Lilli Palmer.

One of a handful of major Hollywood stars of the Golden Age who remained a virtual stranger to film noir, Gary Cooper plays a bachelor nuclear physicist named Alvah Jesper who is working in the United States on the Manhattan Project to build a nuclear bomb. 

Recruited into the Office of Strategic Services (OSS) his mission is to make contact with a Hungarian nuclear physicist, Katerin Lodor, who has been working on the German project to make a nuclear bomb and has escaped into neutral Switzerland.
