Citizenfour is a 2014 documentary film about Edward Snowden's leaks that started the 2013 NSA spying scandal. It was directed by Laura Poitras and contains real footage of several meetings Poitras, journalist Glenn Greenwald, and Ewen MacAskill from The Guardian had with Edward Snowden in Hong Kong as he gave them the leaked classified documents and explained his motivation for doing so. The film received the 2015 Academy Award for Best Documentary Feature.
Citizenfour starts with intro scenes about secret mass surveillance happening in the US after 9/11 and glimpses from the first online conversations Poitras had with Snowden, who was using the pseudonym Citizenfour. We then see footage from a Hong Kong hotel in June 2013 as Edward Snowden meets Potras, Greenwald and MacAskill. Snowden explains how he felt that releasing the documents was the right thing to do, as the mass surveillance done by the NSA had to be exposed, although he thought he would probably end up in prison. Eventually Snowden left Hong Kong trying to get to Ecuador with help from WikiLeaks, but got stuck in a Moscow airport as his American passport was cancelled. He then received asylum in Russia.
