Snowden is a dramatisation of the actual Edward Snowden story, based on the books The Snowden Files by Luke Harding and Time of the Octopus by Anatoly Kucherena.
Joseph Gordon Levitt is hugely believable as Edward, putting in great work into his mannerisms and speech, following his path from his army discharge through to his multiple agency positions and the job that eventually allowed him to extract the information that made him infamous. Shailene Woodley provides support as Lindsey Mills, his on and off partner throughout the entire film.
Oliver Stone seems to have depicted Edward Snowden as a perfect hero in this, he never seems to have put a foot wrong particularly in his career, maybe he didn’t but if leads to feeling a bit fairytale-like in my eyes. But then you have to realise that this actually occurred, surveillance was being done and this information was leaked out. Without that there is no story here!
It’s hard to take yourself away from your own feelings on this topic and view this objectively, but it is a well told story. It would be interesting to see a proper documentary on this subject, or read the books that this was based on and see how it compares. But for the moment, this is a very entertaining film.
