One of the standouts from this year’s Sundance Film Festival, where it won the Alfred P. Sloane Feature Film Prize and the Waldo Salt Screenwriting Award is Kyle Patrick Alvarez’s The Stanford Prison Experiment, a riveting drama based on a real-life psychological experiment. Twenty-four young men are assigned to be either prisoners or guards in a pretend jail on the Stanford University campus where play-acting and reality quickly begin to blur. Billy Crudup is the ambitious professor who designed the experiment, starring alongside a kind of supergroup of up-and-coming talent that includes Ezra Miller, Michael Angarano, Tye Sheridan, James Frecheville, Thomas Mann, Moises Arias and Chris Sheffield.
