The filmmaking of Errol Morris never fails to amaze me. He's responsible for some of the great innovations within the documentary form. This particular film picks up what he started with his highly underrated First Person television series. Morris' interviews are unlike any other on-camera interview you've ever seen because his subjects literally looking down the barrel of the lens, not just at the camera. Morris has designed a device called the "Interrotron" which is a camera with a teleprompter mounted in front of the lens. Superimposed on the teleprompter is Morris' image on, creating an situation where the subject is interviewed directly by not only Morris, but the lens of the camera as well. The eye contact that is achieved with the viewer is unparalled.
The greatest strength of Morris' documentaries, though, is his command of words and language. More than any other filmmaker he is a master of weaving and juxtaposing words together. And, the way he uses people's facial expressions as punctuation and exclamation is nothing short of masterful.
