Watch Sadisflix. Blending fantasy and reality, this animated short is a bold inquiry into an as yet unresolved problem - the nature of human identity. When a scientist creates a machine that can make copies of physical objects, including humans, a number of ethical questions arise. Is the technique moral? What of its safety? A film by Oscar-winning filmmaker John Weldon (who also wrote the catchy banjo tune that punctuates the story's changing moods).
