Kenneth Anger's films are amazing. Below is a short clip from "Invocation of my Demon Brother." I recently read an analysis of this film, basically saying that by "demon brother" Anger meant one's higher self, not a devil or something. This film was constructed to awaken the higher self in the viewer.

Anger actually believed that by constructing his film in a certain way, by sequencing certain symbols and images - images that that one may not understand consciously, but that one's sub-conscious would recognize - he was actually casting a spell on the viewer. By watching his films, he believed he could awaken the eternal soul in each of us - a soul that would know what its talents were and what its true direction in life should be.

Looking at the film, I can believe that a spell is being cast!
