Errol Morris broke cinematic ground with The Thin Blue Line, establishing a new genre in the non-fiction feature by creating a fascinating reconstruction and investigation of a brutal and senseless murder.

The case in question is centred on the 1976 murder of a Dallas policeman. The murder remained unsolved for over a month until the Dallas police department received word that 16-year-old David Harris had been arrested in Vidor, Texas, after having bragged to friends that he killed a Dallas cop. Although the murder weapon was found in a nearby swamp, Harris later insisted that his boasting was meant only to impress his friends and insisted the real murderer was a hitchhiker he had picked up earlier that day named Randall Adams.

Morris assembles diverse interviews, photo montages, film clips and reenactments of the crime to make a strong case for Adams's innocence, leading to a shocking finale. Show less
