The new film "The Stanford Prison Experiment" recounts a psychological study gone awry. In 1971, a Stanford professor enlisted 24 students to participate in a simulation of life in prison.  

Half of them were assigned roles as prisoners - the other half were told to play guards.

The film was based in large part on video and audio recordings of the famous experiment.  

We talk with the real life professor behind the experiment - Dr. Phillip Zimbardo.
