Dangerous Crossing (1953)

Dangerous Crossing (1953) is a maritime murder conspiracy mystery paranoid woman heiress in distress missing husband silly-newlywed-woman version of the well tested film noir trope of the vulnerable woman, lost in a world of romance that is fear-bitten, weird and underwritten by criminal conspiracy.

That most classic of mystery setups is no longer employed by the movies, the one in which all the world seems to be a conspiracy. No, madam, the purser has not seen your husband. No, madam, this is not your cabin and your bags were never here, your husband was never on this ship. This story is used again and again by da moviemakers, and here it is in a well-formed and perfect trope, creating rough ripples and mystery.

5 Fingers (1952)

5 Fingers (1952) is an espionage noir thriller drama directed by Joseph L. Mankiewicz and produced by Otto Lang. 

The screenplay written by Michael Wilson was based on the 1950 book Operation Cicero (original German: Der Fall Cicero) by Ludwig Carl Moyzisch, Nazi commercial attaché at the German embassy in Ankara, Turkey (1943–44).

James Mason plays the spy on a mission, darkly manoeuvring around in in ambience of espionage rather well, with his dark and sneaking ways, selling big secrets to some big Nazis.

Fabulous and famous, the spy code-named Cicero was one of the biggest names of World War II. The resulting drama film about the trusted but hugely amoral Albanian valet who had superb access to British secrets, was thrilling and cerebral and different enough to be nominated for two Academy Awards: Best Director for Mankiewicz and Best Screenplay for Wilson. 

The Day The Earth Stood Still (1951)

The Day The Earth Stood Still (1951) is the quintessential high quality high concept high tension classic Hollywood 1950's science-fiction presentation.

The nascent and sudden re-invention of the science fiction film in the 1950s does inevitably draw on film noir style when need be.

And although the themes are of a universal and global nature, not quite the subjective and local tendency in film noir, there are still film techniques and themes aplenty which crossover between the film noir of its day and the science fiction.

Directed by Robert Wise The Day The Earth Stood Still (1951) is spritely, earnest, playful, philosophical, funny, serious and has distinct Bernhard Hermann music, as well as the most irresistible use of the theremin in film history.
