The Guardian's review.

Adam Curtis’s beautiful, gripping film unravels a story of violence, bloodshed and bitter ironies. Beginning with a fateful meeting between President Roosevelt and King Abdulaziz of Saudi Arabia, Curtis delves into a mass of historical archives to shed light on Afghanistan and the west.

The film was quite something. When I heard it was “found footage” I thought it was going to be something else. I still wish it had been that, but what it is still amazing. Definitely worth watching.
