Mad medics... sinister surgeons... psychopathic psychiatrists. We put our trust in them. They say they want to help, to cure, to relieve pain and soothe suffering. They claim those experiments they've been performing are for the greater good of mankind. But what if they actually want the opposite? What happens when doctors are dead set on researching the strange, the bizarre, the weird? What happens when all that scientific and medical knowledge only results in the creation of unimaginable horror? Ever since the dawn of cinema, filmmakers have been depicting on screen the potential outcomes of medical madness and science gone sick. John Llewellyn Probert takes a detailed look at the history of one of the most enduring archetypes in cinema, with an introductory overview of the genre followed by reviews of over 200 key mad doctor movies. In addition to critical appraisal, the author's own medical background allows him to provide a unique insight into just how well the filmmakers have done their homework.
