Yale University, 1961. Stanley Milgram designs a psychology experiment that still resonates to this day, in which people think they’re delivering painful electric shocks to an affable stranger strapped into a chair in another room. Despite his pleads for mercy, the majority of subjects don’t stop the experiment, administering what they think is a near-fatal electric shock, simply because they’ve been told to do so. With Nazi Adolf Eichmann’s trial airing in living rooms across America, Milgram strikes a nerve in popular culture and the scientific community with his exploration into people’s tendency to comply with authority. Celebrated in some circles, he is also accused of being a deceptive, manipulative monster, but his wife Sasha stands by him through it all.

Led by a gripping performance from Peter Sarsgaard, Experimenter uses a fact-based story to pose thought-provoking questions about human nature.
