The film, a remake of the 2001 German film "Das Experiment," is a dramatic retelling of the infamous Stanford Prison Experiment. For those of you who aren't pointed-heady, New Yorker magazine reading elitists, in 1971 a team of psychiatrists at the august university decide to construct a make-believe prison in a basement and gathered some two dozen subjects to take the roles of prisoners and guards.
It's a great conceit for a film.

As the poster makes clear, Brody stars as a prisoner, while Whitaker plays one of the guards. You can see stills of the film over at Bloody Disgusting.
