He is perhaps best known for his 1988 documentary The Thin Blue Line, commonly cited among the best and most influential documentaries ever made.

Teleprompters are used to project an image on a two-way mirror. Politicians and newscasters use them so that they can read text and look into the lens of the camera at the same time. What interests me is that nobody thought of using them for anything other than to display text: read a speech or read the news and look into the lens of the camera. I changed that. I put my face on the Teleprompter or, strictly speaking, my live video image. For the first time, I could be talking to someone, and they could be talking to me and at the same time looking directly into the lens of the camera. Now, there was no looking off slightly to the side. No more faux first person. This was the true first person.
