This is an amazing film and one that serious film buffs need to see. However, while it is clearly an example of Film Noir, it represents a very realistic style of Noir--lacking the dramatic excesses of some (such as KISS OF DEATH and its wheelchair scene) or super-snappy dialog (like DRAGNET). I actually like all three types of Noir films but when it comes to realism, this film ranks up there with HE WALKED BY NIGHT and T-MEN--and this is certainly good company.
The movie is a step-by-step case study of a crime being organized, executed investigated and resolved. While it could have been shot documentary-style (like a few Noir films, such as NAKED CITY), it was handled like a traditional crime drama except that the focus tended to shift back and forth between the criminals and the police--though the focus tended to be on the criminals a bit more often. This really helped make the movie exciting and worked very well. What also helped the movie was the exceptional acting by mostly unknowns or long-time character actors. Good Noir usually does NOT star big names and having the film anchored by Sterling Hayden (who was amazing), Sam Jaffe and Louis Calhern was an excellent move. To assist them were some other exceptional actors, such as James Whitmore and Marilyn Monroe (in a small but exceptional role).
However, despite the amazing acting, the biggest star of the film was the taut script. From start to finish, it sparkled and abounded with realism and an unflinching message that crime doesn't ultimately pay. The total package is one of the best Noir films ever--only exceeded by a small number of movies (such as my favorite Noir, THE KILLERS). See this film!
By the way, please take a look at the very amazing biography of Sterling Hayden on IMDb. I did and was totally blown away--what an amazing life he led. It all sounded so amazing that if they turned it into a film, many would think it was fiction!!
