The Real Deal
I concur strongly w. Chris White's comments. I just took an Unknown Film Noir class from Brandon Lyndon at Facets (excellent on all counts), and happened to spot this on a library's shelves.
The cinematography is so gorgeous and complex visually, I was tempted to stop and explore it, but the story moves at NASCAR speed, so I plunged ahead. Scenes which in most films would be throwaways are jammed with tension and character development. While the score uses a theremin, I found the music unobtrusive.
