Acclaimed documentarian Laura Poitras is not afraid. For years, she’s made films that examine subjects that are eminently hard to access, but her resolute pursuit of these stories has edified our understanding of this opaque world. Her last effort, Citizen Four, won an Oscar for documenting Edward Snowden as he tried to outrun U.S. authorities after he leaked National Security Agency secrets. Risk delves once again into the shadows of our government as it unpacks the complicated story of Julian Assange of WikiLeaks. Assange is, of course, a controversial figure, so much so that Poitras openly wrestles with the various dimensions of his character during the film, which only makes Risk that much more fascinating.
