Brubaker (1980) staring Robert Redford, Jane Alexander, Wilford Brimley, and Morgan Freeman: Based on the true-life story of a concerned warden who takes on the dangerous job of correcting horrible abuses in an Arkansas prison farm. It is an excellent illustration of the challenges confronting a manager who seeks to make broad sweeping changes when there is resistance from staff, customers (prisoners), and the institutions that oversee the prison's operations.   The movie received an Academy Award nomination for Best (Original) Screenplay.

Lean on Me (1989) staring Morgan Freeman and Robert Guillaume: Based on the true story of Joe Clark, an obsessed, disciplinarian of a principal who had a mandate to improve school performance.  This required turning a disaster of a high school into a halfway civilized place of learning, populated by passable students.  It is another illustration of the problems facing change agents and the wide variety of source of resistance to the changes.  It is also a good illustration of the difference that leadership can make in improving organizational performance.
