Due to my location I haven't yet had the opportunity to see "Slave Play" but this "documentary" by Harris seemed more like an obvious vanity piece rather than any kind of an exploration of the play or its process. Most of the film is devoted to watching Harris talk ad nauseum about himself to a group of actors; I found his hyperactive, stream-of-consciousness, all-over-the-place manner become increasingly grating as the film progressed. In one particular scene the actors are shown sitting with their backs to him and they look as though they've become as weary and annoyed with hearing him talk about himself as I had.
What was the purpose of making this film? After it was over, I found myself losing interest in wanting to see the actual play.
