After checking out your post on The Magic Flute, I thought I would make a suggestion, Angie. There’s a movie called Shirin by Abbas Kiarostami that you shoud check out.
For the entire length of the film, we as the audience are actually watching an audience on screen watch a film. We can hear the movie they’re watching, and see the light from the movie as it changes and flickers on their faces as they sit in their dark theater. The film they are watching though is not our focus. Instead it is the audience themselves, watching us in a fashion, scrutinizing us as we scrutinize them.
Here’s a link to a review Maia wrote about it on our film blog!
