This teaser gives us no footage but some highlights of the now (overly) familiar Edward Snowden story- although after last year's Citizenfour I wonder how much this is really necessary. Joseph Gordon-Levitt is playing him here, but Oliver Stone hasn't made a decent movie in many years (not since what, Nixon?) and with his trademark preachiness I'm not sure this particular issue will play to his strengths. But who knows, I guess he might be due for a comeback. It's coming out at Christmas.
