Academy Award-winning film maker Errol Morris made waves as he took on a misacarriage of justice with his film "The Thin Blue Line."  A year after that film was released, the man Morris contended was wronged was released from prison.

Now Morris is looking at a more famous murder conviction, that of Jeffrey MacDonald.  The Green Beret and Army doctor convicted of killing his family in the 1970s was the subject of the best-selling book "Fatal Vision."

Morris contends in his own book "A Wilderness of Error" that MacDonald was railroaded and that a volume of unheard evidence casts doubts on the famous murder case.

Errol Morris discussed the MacDonald case and the power of narrative in criminal cases with Steve Fast.
