This short film is about Don the cockroach which plays in the house, and does things cockroaches do. Or may be it is not about Don, may be it is about something bigger than a cockroach. Maybe it is not the good animation ? Or maybe it is really about Albert Einstein ?
Terry Gilliam was 28 at the time and if you are attentive, you can recognize all his main themes in this short 8 minutes movie which is as absurd as innovative.
