Oliver Stone’s biopic of NSA whistleblower Edward Snowden has reached post-production and now, the first trailer for the flick is online.

The film, based on the books The Snowden Files: The Inside Story of the World’s Most Wanted Man by Luke Harding and Time of the Octopus by Anatoly Kucherena, stars Joseph Gordon-Levitt (think Inception, The Dark Knight Rises and Looper) as Snowden and Shailene Woodley as his girlfriend Lindsay Mills.

Nicholas Cage also makes an appearance as a senior intelligence official, we’re told.

The trailer doesn’t reveal too much but it does set the tone for what’s likely to be a great watch regardless of your stance on Snowden.

Snowden: An Oliver Stone Film is slated to hit theaters this Christmas.
