Tales of horror have always been with us, from Biblical times to the Gothic novel to successful modern day authors and screenwriters. Though the genre is often maligned, it is huge in popularity and its resilience is undeniable. Marc Blake and Sara Bailey offer a detailed analysis of the horror genre, including its subgenres, tropes and the specific requirements of the horror screenplay. Tracing the development of the horror film from its beginnings in German Expressionism, the authors engage in a readable style that will appeal to anyone with a genuine interest in the form and the mechanics of the genre. This book examines the success of Universal Studio s franchises of the 30s to the Serial Killer, the Slasher film, Asian Horror, the Supernatural, Horror Vérité and current developments in the field, including 3D and remakes. It also includes step-by-step writing exercises, annotated extracts from horror screenplays and interviews with seasoned writers/directors/ producers discussing budget restrictions, screenplay form and formulas and how screenplays work during shooting.
