These are outstanding films for anyone engaged in confronting the global surveillance state. They may well contain lessons for the future.
Laura Poitras' "Citizenfour" is a beautifully filmed documentary about the odyssey of Edward Snowden, the independent whistleblower on the National Security Agency. Snowden on the run is filmed surreptitiously in a Hong Kong hotel room and briefly seen in Moscow, and comes across as an immensely likeable, human and compelling human being under conditions that would drive many people beyond paranoia. Poitras is an utterly non-intrusive presence, invisible in the room, and whose email messages with Snowden (known as "ES") convey a sense of curiosity and urgency that makes her altogether human.
