Update: Turns out that the site that was previously hosting Citizenfour had imported the film illegally and the free stream was not approved by the filmmakers. (You can read more about that here.) The movie can be seen in some US theaters or you can find it on HBOGo.
And you can always read this interview with filmmaker Laura Poitras.
Sorry for the confusion.
Previously: Citizenfour, the Oscar-winning documentary about Edward Snowden and the NSA leaks that sent him on the run, is streaming for free online through Thought Maybe.
After the film won Best Documentary Feature at the 2015 Academy Awards a week ago, Snowden congratulated filmmaker Laura Poitras in a statement through the American Civil Liberties Union, writing: “My hope is that this award will encourage more people to see the film and be inspired by its message that ordinary citizens, working together, can change the world.”
