Where can I watch Orwell: 2+2=5 in United States?

George Orwell was one of the most visionary authors of the 20th century, whose novels 1984 and Animal Farm foretold a chilling, authoritarian future. Acclaimed director Raoul Peck interweaves clips, readings from Orwell's diary, cinematic references, and modern-day footage to craft not only a portrait of the writer, but a fresh take on how prophetic his work has become.
