Winner of the Sundance Film Festival's Grand Jury Prize and Alfred P. Sloan Award, Primer tells the story of two small time engineers that trip upon an invention that far surpasses their aspirations. "An ingenious movie about the perils of ingenuity. Invigorating. Like 'Pi' or 'Memento', 'Primer' is the kind of movie likely to inspire both imitators and cultists. Carruth has invented something fascinating." (A.O Scott, The New York Times)
