Dr. Jekyll and Mr. Hyde (1941)

Dr. Jekyll and Mr. Hyde (1941) is an atmospheric horror science fiction mystery movie adaptation of the Robert Louis Stevenson novel The Strange Case of Dr. Jekyll and Mr. Hyde, that stars Spencer Tracy, Ingrid Bergman and Lana Turner.

While not a film noir in the conventional mode nor even much in the capacity of the subject matter and story, Dr. Jekyll and Mr. Hyde (1941) is classic film noir inasmuch as it introduces the style within its full dramatic flow.

Yet as far as the noir, ambivalence and duality are pushed to the extremes in this cracker of a science fiction thriller, with Spencer Tracy who had been symbolising rectitude for many a cinematic year preceding. 

Bad Day at Black Rock (1955)

Bad Day at Black Rock (1955) is a color film noir classic with a neo-Western setting, offering a thrilling paranoiac small-town murder story in which Spencer Tracy roughs up against some brilliantly played rough and tough local talent in a desert town.

Directed by John Sturges and starring Lee Marvin and Ernest Borgnine, Bad Day at Black Rock is the sure-fire best deepest and most entertaining colour film noir of the era — if indeed we are classifying it as such!

The film was based on a short story called Bad Time at Honda by Howard Breslin, published by The American Magazine in January 1947. Filming began in July 1954 and the movie went on national release in January 1955. It was a box office success and was nominated for three Academy Awards in 1956. In 2018, it was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant"

The bad-ass desert town-dwellers, led by film noir's own Robert Ryan are as immortal immoral crew as cinema ever created. They would be great with their own mini-series, Thugs of Black Rock, or similar.
