Really interesting bio type story - I had no opinion on him either way till watching this and now I admire his resolve and pursuit of justice. I was particularly fascinated to find he was initially raised as part of "the family" aka "Children of God" cult and spent much of his formative years on the run from it with his mother. If you're not familiar with this quite notorious group look it up - a lot of creepy stuff went on. He switched schools several times per year and was also homeschooled often - pretty much a life on the run. FYI - there is a documentary about this group on HBO but it's kinda dreary and leaves off on a negative note.
The story outlines his early years and up until he was initially holed up in the Equadorian embassy in London (and he's still there now, as of July 2016). Check out
about Snowden if you're interested in tech whistleblowers/hackers. I actually watched that first and it pricked my interest in Julian Assange, as he attempted to help Snowden get out of Hong Kong and to a country of refuge. I haven't (yet) watched the movie about Snowden - CitizenFour is a documentary - but I will at some point I'm sure.
