La sottile linea blu

A film that successfully argued that a man (Randall Dale Adams) was wrongly convicted for murder by a corrupt justice system in Dallas County, Texas.

Morris was originally going to film a documentary about prosecution psychiatrist, Dr. James Grigson, known as Doctor Death, who testified in more than 100 trials that resulted in death sentences. In almost every instance, Dr. Grigson would, after examining a defendant, testify that he had found the individual in question to be an incurable sociopath, who it was "one hundred per cent certain" would kill again.

This lead Morris to find an example, Adams, where this "incurable sociopath" status was in doubt. But we also still have that critique of Grigson -- we see what he said about Adams, a man with no history of criminal acts or violence, after only fifteen minutes with him.

This change in focus lead to a better film, most likely (though Erroll Morris has an incredible track record for good documentaries). We now get to see a wider picture of eyewitness testimony, the prejudice of the area (which includes a thriving KKK) and more.

Adams' case was reviewed and he was released from prison approximately a year after the film's release. Now that is the sign of a powerful film, and what makes documentaries so great.
