Short documentary directed by George Lucas about '60s DJ "Emperor" Bob Hudson, who was something of a big noise on the US radio back in the day. It was directed by George Lucas when he was a student, and young Master Lucas proves himself rather adept at making very little stretch a long way as we learn a lot about the Emperor's style but very little about the man himself. Shots of Hudson at work alternate with rather arty shots of 60s US street culture to surprisingly good effect, and Lucas's film has an energy that its portly subject lacks.
