IFC Films has released the first theatrical trailer for this year's Sundance Alfred P Sloan Feature Film Prize-winning film The Stanford Prison Experiment. Directed by Kyle Patrick Alvarez, the film chronicles Dr. Philip Zimbardo's infamous study on the psychology of imprisonment at Stanford University in the summer of 1971. Twenty-four male students were randomly assigned the role of prisoner or guard before being placed in a simulated jail and rapidly, unsettlingly embodying their assigned roles. As the new trailer puts it: "the results shocked the world".

The Stanford Prison Experiment premiered at this year's Sundance Film Festival, where it was awarded the Waldo Salt Screenwriting Award in addition to the Sloan Prize. The film stars Billy Crudup as Dr. Philip Zimbardo, as well as Michael Angarano, Tye Sheridan, Johnny Simmons, Ezra Miller as participants in the study and Olivia Thirlby as Dr. Zimbardo's wife Dr. Christina Maslach.

The Stanford Prison Experiment opens in theaters on July 17.
