The Mob is a 1951 American film noir crime-thriller produced by Columbia Pictures, directed by Robert Parrish, and starring Broderick Crawford. The screenplay, which was written by William Bowers, is based on the novel Waterfront by Ferguson Findley. Plot Johnny Damico, a detective going home on a rainy night, finds himself just a few feet from a shooting on a dark street. The gunman claims to be a detective from another precinct, flashing a real badge, and then slipping away. Damico discovers that the victim of the shooting was a witness who was to have appeared before a grand jury investigating waterfront crime, and that the same man who shot him also murdered the chief investigator on the case just a few hours earlier (which is where the badge came from).

He is befriended by Tom Clancy, a fellow longshoreman who lives at the same hotel. There the two frequently meet after work for drinks, which are invariably served to them by a bartender nicknamed "Smoothie". Damico, still posing as Flynn, now manages to hook up with union thug Joe Castro, who tries to frame Damico for murder by having his strong-arm goon Gunner temporarily seize the undercover cop's own pistol to shoot and kill a potential stoolie, Culio. Castro then has Gunner return the pistol to Damico, who the next day is arrested for the murder by a crooked police sergeant named Bennion, although Police Lt. Banks manages to spring him. After following one blind alley involving a federal agent—the
