Peter Sarsgaard talks about his role in the experimental 'Experimenter'

Stanley Milgram is not a household name. But even those who have never heard of the social psychologist (1933-1984) may be aware of his landmark Yale experiment on obedience to authority. In a series of experiments, subjects were instructed to administer a series of increasingly painful electric shocks to a volunteer taking a memory test, as punishment for a wrong answer. Surprisingly, 65 percent of the subjects continued to deliver volts, despite cries of pain.
