First, Fred Williamson struts his macho magnetism as a Chi-town cop who teams with beautiful policewoman Maud Adams to go against an ex-con and his own crooked compadres. Bo Svenson and singer Phyllis Hyman also star in the furious, rock 'em-sock 'em flick "Soda Cracker." AKA: "The Kill Reflex." And, the spirit of 1970s "blaxploitation" films is resurrected in "Original Gangstas," the actioner starring Williamson as a former gangbanger who returns to his Midwest home to battle a group of punks terrorizing his family and his old neighborhood. Joining him are Pam Grier, Jim Brown, Richard Roundtree, and Ron O'Neal; directed by Larry Cohen ("Black Caesar").
