American director Laura Poitras has released the first trailer for ‘Citizenfour’, the documentary that entails her time reporting on the NSA scandal and whistleblower Edward Snowden. It’s a tension-fueled trailer setting the scene for what Poitras aimed to record. The documentary will follow Poitras and journalist Glenn Greenwald as they meet Snowden in Hong Kong, where he tells them what the intelligence agency actually has been compiling about American citizens and other persons of interest. The documentary – a co-production with Steven Soderbergh – premiered during New York Film Festival and is scheduled for release in the UK on October 17.
