The Stanford Prison Experiment

They were given 2 weeks. It lasted 6 days.

This unsettling fact-based drama reproduces the notorious, still controversial psychology experiment from 1971 in which a bunch of 24 Californian university students volunteered to take part in a study into prison life. As we discover, a flip of a coin decides who will be mock guards and who prisoners. But the role-playing soon gets alarmingly out of hand.

Ezra Miller and Michael Angarano stand out among the students, while Billy Crudup plays the tunnel-visioned academic in charge, Philip Zimbardo. The film is tough going in places but offers a chilling study into the psychology of authority and the abuse of power.

Certificate 15. Runtime 119 mins. Director Kyle Patrick Alvarez
