Occasionally Allied Artists was able to produce a first rate serious film unrelated to their usual formularized output.'The Gangster' is an unconventional crime picture that concentrates on the latter end of a racketeer's career,the effects rather than the causes of his persona,his neighborhood of operations,and the people who have been corrupted by his contact. As the protagonist Barry Sullivan essays a suitably morose,hardened individual driven by desperation to hold onto his rapidly crumbling kingdom.Desperate too are the pathetic bystanders who will be effected if this petty prince of rackets should fall to the machinations of a rival mob.Belita is a fashion socialite whom Sullivan uses but cannot love.Akim Tamiroff is terrific as the owner of a seemingly innocuous ice-cream parlor where Sullivan's influence has set in motion the tragic events that follow.Also well-cast are Joan Lorring as an adoring counter girl,John Ireland as a hooked gambler,Harry Morgan as an amusing soda-jerk,and every film buff's "favorite" New York thug,Sheldon Leonard as the leader of the new mob organization.
