I have no idea how old the actual documentary was, but I was trying to remember it since it was pretty good.
The guy was British I believe, I saw it in a class about either... literature or art. I can't recall. I think he self described himself as a socialist critic? But a good chunk of it was the experience of viewing art is very different than "watching" art on TV. He used an example of a famous picture of Jesus being crucified and pointed out how your feelings about the painting can be easily manipulated with video editing and music. He ran through the shots three different times, each with different music, pans and cuts. It then cuts to him just standing in a museum with no effects on an ordinary day, just watching the painting.
He also talked about the difference between view the "real" painting Mona Lisa, and how that differs from viewing it on a stamp, or computer picture, or copy. Subtle things, but ones that you miss if you aren't actually looking at the real thing.
In general I thought it was one of the better documentaries I watched in school, and I just can't recall who it was, or how to find it.
