The eerie time of night when all is quiet and still, and most people are asleep, is the perfect setting for filmmaker Laura Poitras to investigate the elusive journey from the National Business Park to a windowless skyscraper in downtown Manhattan. Elevated by the understated narration of guidelines from classified National Security Agency documents (read by familiar voices Rami Malek and Michelle Williams), this is a thrilling proposal of the degree to which government secrets are unknown to the public. Directed with Henrik Moltke—a journalist who collaborated with Poitras in reporting on the Snowden documents—Project X is an exemplary dissection of espionage. KR
