The real-life "Machine Gun" Kelly was a clumsy, two-bit petty thief, goaded into bigger and badder things by a publicity-hungry wife; legend has it that when Kelly was finally captured by the FBI, he had a smile on his face, as if relieved to get away from the gorgonlike Mrs. Kelly. This film version of Kelly's life alters the facts considerably: as played by Charles Bronson, "Machine Gun" is a cold-blooded sadist who kills because he's sensitive about his height. Together with his ever-lovin' moll Flo (Susan Cabot), Kelly decides to top off his criminal achievements with a high-profile kindapping, a decision that leads to his bloody downfall. Comedian Morey Amsterdam delivers a surprisingly effective performance as a stool pigeon who "gets his" from the business end of Kelly's eponymous weapon. Directed with sweaty intensity by Roger Corman, Machine Gun Kelly was originally released on a double bill with The Bonnie Parker Story.
