With 250 entries, this filmography and resource is the guide to all things lycanthropic and a fascinating compendium of comparative mythology and folklore. Delving into the 15th century to uncover the origins of the werewolf legend, it is an eye-opening, blood-pounding tour through the ages, landing on the doorstep of creatures like hirsute mass-murderer Charles Manson and canine-directed Son of Sam. A helpful chronology of lycanthropic activities dates back 140,000 years, to the first mixing of human and lupine blood.
