Off duty police detective Johnny Damico (Broderick Crawford) lets a killer slip through his hands after witnessing a mob hit. Damico is given a chance to redeem himself by going undercover to break up a waterfront crime racket and find the kingpin that ordered the hit. Damico under the assumed identity of small time New Orleans hoodlum Johnny Flynn, infiltrates the docks to find the 'big guy' known only as Blackie Clegg. Along the way Damico comes across an assortment of characters played by, at the time, relatively unknown actors like Ernest Borgnine, Neville Brand, Richard Kiley, and John Marley. Look for Charles Bronson in one of his earliest screen appearances in an uncredited role as a dock hand.
Director Robert Parrish works what might have been routine police procedural crime drama into an edge of the seat mystery. A lot of the credit has to be given to writer William Bowers who Parrish teamed up with on his previous movie Cry Danger starring Dick Powell. Both enjoy a fast paced script with tongue in cheek banter, hinting of the same style that Bowers would use almost twenty years later when he wrote the script for Support Your Local Sheriff! While an actor like Powell would seem better suited for this type role, Crawford just off an Oscar win for All the Kings Men two years before, comes off surprisingly natural as a wise cracking undercover cop.
The Mob though listed as film noir really isn't noir in the classic sense though it does have some of the elements. The Mob is an enjoyable 1950's style mystery crime drama. The run time of 87 minutes breezes by and keeps you guessing. Fans of the genre will enjoy this one.
