It Seems that the Sharp, Dark, Rough World of Film-Noir was just too Much for the Newly Emerging Conservative 1950's.
The Forces that be were Out to Tame Film-Noir and Morph the Style into Police Procedurals, and Other Easily Digested Movies "Sweetening" the "Sour".
Case-in-Point, "Two of a Kind", this one had All the Signs of the Genre .
But were Proven a Slight-of-Hand, sort of, or a Mis-Direction.
Starring Noir Icon's Edmond O'Brien and Lizabeth Scott and a Poster that Shows Not a Hint that it will Take a "Detour" to Comedy, and a Light-Hearted Approach as the Con-Game is Played-Out.
When Terry Moore's "Screwy" Character Shows-Up, it No-Longer even Tries to Maintain its Bona-Fides as a Film-Noir.
It has One Extremely Disturbing Scene, "The Car-Door", but the Rest of the Story is so Breezy and Aloof as to be Distracting to Anyone who was Expecting a More Serious, Gritty Story.
Overall, it can be Enjoyed as a Light-Crime Con-Game with Good Actors and Good Cinematography.
The Genre of Film-Noir, to This Day, is Exploited and the Label is Slapped on Movies that Just Don't Cut-It. The True Essence and Meaning of the Descriptive has been Lost Almost Completely.
This Whole Thing Started Around 1950-51 and is Still Around Today.
For Film-Noir Purist, be Prepared for a Let-Down.
