Street Smart (1987)

Synopsis
Jonathan Fisher (Christopher Reeve) is a newspaper reporter who becomes a celebrity when he writes a fictitious exposé on prostitution. The story of the high-living pimp is too close a resemblance to real-life flesh pedlar Fast Black (Morgan Freeman), and Jonathan is jailed when he refuses to turn his papers over to the local district attorney. In jail for suspicion of murder, Black tries to silence the reporter who created the sensational fabrication. ~ Dan Pavlides, All Movie Guide
