Snowden documentary to get world premiere at New York Film Festival

Laura Poitras' documentary Citizenfour, about the whistle-blower Edward Snowden, will have its world premiere on October 10 at the New York Film Festival, after it was announced as a late addition. Poitras was working on a film about national security and privacy in America when Snowden contacted her – using the name "citizen four" in encrypted emails – about thousands of documents revealing the US National Security Agency's collection of phone and email records. Poitras filmed their subsequent interviews, which appear in the film; and she shared the Pulitzer Prize for Public Service awarded this year to The Washington Post and The Guardian newspapers for their NSA revelations. The New York Film Festival director Kent Jones said the film was a character study of Snowden, a real-life suspense story and a chilling exposé. – AP
