You can t say the mob wasn t warned about John Shaft. He s a bad dude, a numbers racketeer cautions them. Now, Shaft himself will deliver that message in a way New York City's wiseguys understand. Richard Roundtree reunites with the director (Gordon Parks) and screenwriter (Ernest Tidyman) of 1971 s trendsetting Shaft for Shaft s Big Score!, the second of Roundtree s three movie portrayals of the street-smart, leather-jacketed private investigator. This time, the blown-to-kingdom-come murder of a client plunges Shaft into a case that bounces him like a pinball between the 133rd Precinct and competing mobs. But the players are about to be played in this rousing and entertaining thriller (Newsweek).
