Some movies romanticize the life of crime, or make the criminals into sympathetic characters, but Roger Corman’s “Bloody Mama” goes in the opposite direction with its depiction of the Barker crime family of the 30’s and their ruthless murders, sadism, incest, drug addiction, and insanity. It’s a morbidly colorful mixture of negative southern poor white trash stereotypes, encapsulated in a family of sociopaths, with a vintage Shelly Winters bringing her trademark intensity to the role of Ma Barker and a great cast as her sons and their associates, including Don Stroud, Robert Walden, Bruce Dern, Diane Varsi, and Robert DeNiro. A mishmash of humor and repugnancy, it’s definitely not for the squeamish.
