Snowden: new trailer for Oliver Stone's thriller starring Joseph Gordon-Levitt

The latest look at Oliver Stone’s real-life espionage drama concentrates on Edward Snowden’s (Joseph Gordon-Levitt) relationships – with his girlfriend (played by Shailene Woodley) and with the journalists and film-maker in whom he confides: Glenn Greenwald (Zachary Quinto), Ewen MacAskill (Tom Wilkinson) and Laura Poitras (Melissa Leo). The film, based in part on Guardian journalist Luke Harding’s book about the episode, is due to be released in the US on 16 September
