Yale University, 1961. Stanley Milgram (Peter Sarsgaard) designs a psychology experiment that still resonates to this day, in which people think they're delivering painful electric shocks to an affable stranger (Jim Gaffigan) 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 (Winona Ryder) stands by him through it all. EXPERIMENTER invites us inside Milgram's whirring mind in this bracing portrait of a brilliant man whose conscience and creative spirit continues to be resonant, poignant, and inspirational.
