Book excerpt: Serial killers, mass murderers, spree killers, outlaws, and real-life homicidal maniacs have long held a grim fascination for both filmmakers and viewers. Since the 1970s, hundreds of films and television movies have been made covering killers from Charles Manson to Ted Bundy and the Zodiac Killer creating a uniquely morbid sub-genre within horror and thrillers. This collection of interviews sheds light on 17 filmmakers and screenwriters who tackled this controversial subject while attempting to explore the warped world of infamous killers. The interviews include John McNaughton (Henry: Portrait of a Serial Killer), Tom Hanson (The Zodiac Killer), David Wickes (Jack the Ripper), Chris Gerolmo (Citizen X), Chuck Parello (The Hillside Stranglers), David Jacobson (Dahmer) and Clive Saunders on his ill-fated experience directing Gacy. Offering candid insights into the creative process behind these movies, the interviews also show the pitfalls and moral controversy the filmmakers had to wrestle with to bring their visions to the screen.
